Question 1Paper-I

In UGC NET Paper-I, the term 'higher education system' in the teaching aptitude unit primarily refers to which of the following?

  1. The structure, governance and processes of universities and colleges Correct answer.
  2. The recruitment norms of primary teachers
  3. The administrative rules of school boards
  4. The financial audit of research grants

Explanation

Teaching aptitude in Paper-I situates pedagogy within the Indian higher education system, covering universities, colleges, regulatory bodies and their processes. School boards and primary teacher recruitment belong to school education, not the higher education unit.

Question 2Paper-I

A researcher studying classroom interaction records whether a teacher praises, questions or ignores each student utterance. Which level of measurement is being used for the variable 'teacher response type'?

  1. Ratio
  2. Ordinal
  3. Interval
  4. Nominal Correct answer.

Explanation

Teacher response type classifies utterances into named categories with no inherent order or numeric distance, so it is nominal. Ordinal would require ranking categories, while interval and ratio require meaningful numeric scales.

Question 3Paper-I

In communication theory, decoding refers to which of the following?

  1. The sender converting ideas into symbols
  2. The medium carrying the message to the audience
  3. The source selecting a channel for transmission
  4. The receiver interpreting the symbols sent by the source Correct answer.

Explanation

Decoding is the receiver's act of assigning meaning to the symbols transmitted by the source. Encoding, by contrast, is the sender's conversion of ideas into symbols, and the channel is the medium of transmission.

Question 4Paper-I

Which of the following best describes the logical fallacy of 'argumentum ad hominem'?

  1. Assuming a conclusion from insufficient evidence
  2. Appealing to popular opinion as proof of truth
  3. Circularly assuming the conclusion as a premise
  4. Attacking the person advancing an argument rather than the argument itself Correct answer.

Explanation

Ad hominem reasoning shifts attention from the merits of a claim to the character or circumstances of the person making it. It is distinct from appeals to popularity, hasty generalization and circular reasoning.

Question 5Paper-I

A student who studies hard, attributes success to effort, and persists after failure most clearly displays which of the following?

  1. An internal locus of control Correct answer.
  2. Diffuse identity status
  3. An external locus of control
  4. Learned helplessness

Explanation

Locus of control concerns beliefs about what determines outcomes; attributing results to one's own effort indicates an internal locus. External locus attributes outcomes to luck or others, and learned helplessness involves giving up after repeated failure.

Question 6Paper-I

In the context of environmental education in higher education, 'sustainable development' is best defined as development that meets present needs without doing which of the following?

  1. Involving government regulation of industry
  2. Compromising the ability of future generations to meet their needs Correct answer.
  3. Permitting economic growth in developing nations
  4. Requiring any use of non-renewable resources

Explanation

The Brundtland formulation defines sustainable development as meeting present needs without compromising future generations' ability to meet theirs. It does not forbid growth or all resource use, but requires intergenerational equity.

Question 7Paper-I

Which of the following is a defining feature of a probability sampling technique in educational research?

  1. Every element of the population has a known, non-zero chance of selection Correct answer.
  2. Participants are chosen because they are easily accessible
  3. Subjects volunteer after an open invitation
  4. The researcher deliberately selects typical cases

Explanation

Probability sampling rests on known, non-zero selection probabilities, which permit estimation of sampling error. Convenience, volunteer and purposive selection are non-probability approaches.

Question 8Paper-I

The 'digital divide' in higher education most directly refers to which of the following?

  1. Differences in the number of online courses offered by universities
  2. The lag between curriculum design and industry needs
  3. Inequality in access to digital devices, connectivity and digital skills Correct answer.
  4. The gap between urban and rural university enrolment only

Explanation

The digital divide concerns unequal access to devices, internet connectivity and the skills needed to use them effectively. It is broader than any single urban-rural enrolment gap or course-count difference.

Question 9Paper-I

A teacher uses a pre-test and post-test with a single group to evaluate a new method. Which threat to internal validity is most clearly uncontrolled in this design?

  1. Presence of a control group
  2. Use of a standardized achievement test
  3. Maturation and history effects over the study period Correct answer.
  4. Random assignment of participants

Explanation

A one-group pretest-posttest design lacks a comparison group, so changes over time due to maturation or external events (history) cannot be separated from the treatment effect. Control groups and randomization are precisely what this design lacks.

Question 10Paper-I

In a normal distribution, approximately what percentage of cases falls within one standard deviation of the mean?

  1. 95 per cent
  2. 68 per cent Correct answer.
  3. 99 per cent
  4. 50 per cent

Explanation

The empirical rule states that about 68 per cent of observations lie within one standard deviation of the mean in a normal distribution. About 95 per cent fall within two standard deviations and about 99.7 per cent within three.

Question 11Paper-I

A researcher computes a correlation of -0.82 between hours of remedial instruction and errors on a mathematics test. Which interpretation is most appropriate?

  1. The correlation indicates a calculation error since it is negative
  2. More remedial instruction is associated with fewer errors, with a strong relationship Correct answer.
  3. The relationship is weak and negligible
  4. More remedial instruction causes more errors

Explanation

A correlation of -0.82 indicates a strong inverse association: as instruction hours rise, errors tend to fall. Correlation does not establish causation, and negative values are perfectly legitimate for inverse relationships.

Question 12Paper-I

A university adopts a policy of continuous internal assessment with feedback after each unit. Which learning principle does this most directly apply?

  1. Criterion-referenced certification of competence
  2. Norm-referenced ranking of students
  3. Formative assessment supporting timely feedback Correct answer.
  4. Summative assessment determining final grades

Explanation

Assessment used during learning to provide feedback and guide improvement is formative. Summative, norm-referenced and certification purposes all concern judgment at the end or relative standing, not ongoing feedback.

Question 13Paper-I

In a classroom, a teacher moves from simple recall questions to analysis and evaluation questions within the same lesson. This practice best reflects which principle?

  1. Norm-referenced testing
  2. Use of only lower-order objectives
  3. Progressive cognitive scaffolding across Bloom's taxonomy levels Correct answer.
  4. Behaviourist conditioning through reinforcement

Explanation

Sequencing questions from recall to analysis and evaluation reflects planned progression through Bloom's cognitive levels, providing scaffolding. It is not restricted to lower-order objectives, nor is it norm-referenced testing or conditioning.

Question 14Paper-I

A research report states that results are generalizable to all Indian university students although the sample was drawn only from one state. Which error is being committed?

  1. Overgeneralization beyond the sampling frame Correct answer.
  2. Failure to report the sample size
  3. Plagiarism of secondary data
  4. Use of an inappropriate statistical test

Explanation

Generalizing to a national population from a single-state sample exceeds the sampling frame and constitutes overgeneralization. The problem is inferential scope, not statistical choice, reporting omission or attribution.

Question 15Paper-I

In a multiple-choice test item, which of the following most improves the item's discriminating power?

  1. Options arranged in no consistent order with overlapping meanings
  2. Options that are all synonyms of the key
  3. A correct option noticeably longer than the others
  4. Distractors that are plausible to students with partial knowledge Correct answer.

Explanation

Plausible distractors attract students with incomplete understanding, so the item separates them from those who know the content. Synonym options, length cues and overlapping meanings reduce discrimination.

Question 16Paper-I

Which of the following best illustrates the use of a blended learning approach in higher education?

  1. Combining face-to-face sessions with structured online activities and resources Correct answer.
  2. Conducting only laboratory practicals
  3. Using a single textbook for the whole course
  4. Replacing all instruction with recorded lectures

Explanation

Blended learning integrates face-to-face teaching with planned online components so the two modes complement each other. Wholesale replacement by recordings is fully online delivery, and single-medium teaching is not blending.

Question 17Paper-I

A researcher wants to compare mean scores of three independent groups. Which statistical technique is most appropriate?

  1. Paired-samples t-test
  2. Chi-square test of independence
  3. One-way analysis of variance Correct answer.
  4. Pearson product-moment correlation

Explanation

One-way ANOVA tests whether means differ across three or more independent groups. The paired t-test handles two related samples, chi-square handles categorical association, and correlation handles covariation of two continuous variables.

Question 18Paper-I

A teacher who suspects a student's essay was generated by an artificial intelligence tool should first do which of the following?

  1. Ignore the matter to avoid conflict
  2. Assign an automatic failing grade without discussion
  3. Publicly accuse the student before the class
  4. Verify against the institution's academic integrity policy and gather evidence of authorship Correct answer.

Explanation

Suspected misconduct should be handled through the institution's academic integrity procedures, with evidence gathered before any finding. Public accusation, automatic penalty without process and avoidance all violate fair procedure.

Question 19Paper-I

Which of the following best characterizes 'inclusive education' at the higher education level?

  1. Admitting students only from a single social category
  2. Lowering academic standards for all students
  3. Designing curricula and environments to accommodate diverse learner needs from the outset Correct answer.
  4. Providing separate classes for students with disabilities

Explanation

Inclusive education anticipates learner diversity in course design and campus environment so that participation is not conditional on assimilation. Segregation, exclusion and blanket lowering of standards misrepresent the concept.

Question 20Paper-I

A researcher uses a Likert scale ranging from strongly disagree to strongly agree. Which property does this scale most clearly provide?

  1. True ratio-level measurement
  2. Absolute zero measurement
  3. Nominal classification only
  4. Ordinal ranking of response positions Correct answer.

Explanation

Likert response categories are ordered from least to most agreement, giving ordinal properties. They lack a true zero and equal intervals, so they are not ratio or interval in the strict sense, and they convey more than nominal classification.

Question 21Paper-I

Which of the following best explains why random assignment strengthens a causal claim in an experimental study?

  1. It distributes known and unknown confounders across groups in expectation Correct answer.
  2. It ensures measurement instruments are valid
  3. It guarantees that the sample represents the whole population
  4. It eliminates the need for a control group

Explanation

Random assignment balances both measured and unmeasured confounders across conditions in expectation, making groups comparable. It does not ensure population representativeness, replace a control group or affect instrument validity.

Question 22Paper-I

A researcher reports a p-value of 0.03 with an alpha of 0.05 but a very small effect size. Which conclusion is most defensible?

  1. The effect size is irrelevant once significance is reached
  2. The result is statistically significant but may have limited practical importance Correct answer.
  3. The result is statistically non-significant
  4. The hypothesis is proven true beyond doubt

Explanation

A p-value below alpha indicates statistical significance, yet a small effect size suggests limited practical importance. Significance does not prove a hypothesis, nor does it render effect size irrelevant.

Question 23Paper-I

In communication, which barrier is illustrated when a lecturer uses unexplained technical jargon with first-year students?

  1. Organizational barrier arising from hierarchy
  2. Semantic barrier arising from specialized vocabulary Correct answer.
  3. Physical barrier arising from noise
  4. Psychological barrier arising from distrust

Explanation

Semantic barriers concern meaning: specialized terms unfamiliar to the audience obstruct understanding. Noise is physical, hierarchy is organizational, and distrust is psychological, none of which is at issue here.

Question 24Paper-I

A study finds that students who use the library more often also achieve higher grades. A reviewer argues the relationship may reflect prior academic motivation. This reviewer is pointing to which issue?

  1. A sampling error
  2. A confounding variable Correct answer.
  3. A measurement ceiling in the grade scale
  4. A ceiling effect

Explanation

Prior motivation could influence both library use and grades, making it a confounder that can create a spurious association. Sampling error concerns sample fluctuation, while ceiling effects concern restricted upper-range scores.

Question 25Paper-I

A university wishes to evaluate whether a new mentoring programme improves retention, using an untreated comparison group and baseline measurement. Which design best fits this requirement?

  1. Cross-sectional survey design
  2. Case study of a single student
  3. Quasi-experimental pretest-posttest design with a comparison group Correct answer.
  4. One-group posttest-only design

Explanation

A pretest-posttest design with a non-equivalent comparison group controls for baseline differences and time trends when random assignment is impractical. Posttest-only single-group, cross-sectional and case study designs cannot support the comparison.

Question 26Paper-I

In UGC NET Paper-I, the unit on teaching aptitude distinguishes 'maxims of teaching' from general teaching methods. Which maxim advises the teacher to proceed from the known to the unknown?

  1. Maxim of simple to complex
  2. Maxim of known to unknown Correct answer.
  3. Maxim of particular to general
  4. Maxim of concrete to abstract

Explanation

The maxim of known to unknown directs the teacher to link new content to what learners already understand, so that unfamiliar ideas are anchored in existing knowledge. It is one of the classic maxims of teaching along with simple to complex and concrete to abstract. Each maxim names a specific sequencing principle, so only the one that explicitly names prior knowledge fits the stem.

Question 27Paper-I

A learner remembers the definition of 'socialisation' exactly as printed in a textbook but cannot explain how a family transmits norms. In Bloom's revised taxonomy, the learner's performance is best classified at which level?

  1. Apply
  2. Understand
  3. Remember Correct answer.
  4. Analyse

Explanation

Recalling a definition verbatim without being able to explain or exemplify it corresponds to the Remember level, which involves retrieving relevant knowledge from long-term memory. Understand requires explaining, exemplifying, or paraphrasing, which the learner cannot do. Apply and Analyse demand using or decomposing knowledge, both beyond this performance.

Question 28Paper-I

In the context of learner-centred education in higher education, which practice is the clearest indicator of formative assessment?

  1. Ranking students on the basis of a single terminal examination
  2. Announcing the weighting of the end-semester examination in the first class
  3. Giving a graded final viva whose marks are reported only after the course ends
  4. Providing ungraded weekly quizzes with immediate feedback that students use to revise Correct answer.

Explanation

Formative assessment is designed to generate feedback during learning so that teaching and study can be adjusted; ungraded quizzes with immediate feedback serve exactly this function. Summative assessment, by contrast, judges achievement at the end of a course. The other options describe summative or administrative uses of assessment.

Question 29Paper-I

A researcher wants to study the reading habits of visually impaired university students, a small and hard-to-reach population. Which sampling strategy is most appropriate?

  1. Snowball sampling starting from a known student network Correct answer.
  2. Systematic sampling with a random start
  3. Simple random sampling from the full university enrolment list
  4. Cluster sampling of whole departments

Explanation

Snowball sampling uses referrals from initial respondents to reach further members of a hidden or hard-to-reach population, which suits a small group that no accessible sampling frame lists. Probability methods such as simple random, systematic, and cluster sampling all require a usable frame that covers the target population. When such a frame is unavailable, referral-based selection is the practical choice.

Question 30Paper-I

Which of the following is the primary purpose of a literature review in a research dissertation?

  1. To prove that the research question is entirely novel
  2. To display the researcher's command of citation formats
  3. To establish the theoretical and empirical context of the research problem Correct answer.
  4. To substitute for the collection of primary data

Explanation

A literature review locates the study within existing theory and evidence, identifies gaps, and justifies the research question. Citation formatting is a presentational requirement, not the purpose of the review. A review never replaces data collection, and complete novelty is neither required nor provable from a review alone.

Question 31Paper-I

A person who deliberately falsifies data in a published paper is primarily violating which principle of research ethics?

  1. Confidentiality
  2. Integrity and honesty in reporting Correct answer.
  3. Beneficence
  4. Informed consent

Explanation

Fabrication or falsification of data breaches research integrity, the duty to report findings honestly and accurately. Informed consent and confidentiality concern the treatment of human participants, while beneficence concerns maximising benefit and minimising harm. The stem describes misconduct in reporting, not a participant-protection failure.

Question 32Paper-I

Which of the following best represents the use of information and communication technology for collaborative learning rather than mere content delivery?

  1. A teacher sends a digital copy of the syllabus to the class group
  2. Students co-author a shared online document and comment on each other's drafts Correct answer.
  3. A teacher uploads recorded lectures for students to watch before class
  4. Students download a scanned textbook chapter from the institutional portal

Explanation

Collaborative learning requires learners to interact and jointly construct knowledge, which co-authoring a shared document with peer commentary exemplifies. The other options use ICT only to distribute or deliver content to individual students. Distribution of material is transmission, not collaboration.

Question 33Paper-I

In the UGC NET Paper-I unit on higher education systems, which body is responsible for coordinating and maintaining standards in Indian higher education?

  1. University Grants Commission Correct answer.
  2. All India Council for Technical Education
  3. National Council of Educational Research and Training
  4. National Assessment and Accreditation Council

Explanation

The University Grants Commission is the statutory body charged with coordination, determination, and maintenance of standards in university education. NCERT works at the school stage, NAAC conducts assessment and accreditation rather than standard-setting coordination, and AICTE covers technical education specifically. The stem asks for the general coordinating body for higher education.

Question 34Paper-I

A speaker uses the phrase 'the report was released by the ministry' but a listener hears 'the report was relished by the ministry'. Which element of the communication process explains this misunderstanding?

  1. Noise affecting the signal during transmission
  2. Decoding of the message by the receiver Correct answer.
  3. Selection of the channel by the source
  4. Encoding of the message by the source

Explanation

Decoding is the receiver's interpretation of the symbols transmitted; hearing a different word and assigning a different meaning is a decoding error. Encoding is what the source does when constructing the message, and channel selection concerns the medium. Noise refers to interference in the signal itself rather than the receiver's interpretation of an intact signal.

Question 35Paper-I

A researcher claims that a new tutorial method caused higher achievement, but students were assigned to the tutorial group by their own choice. Which alternative explanation most threatens the causal claim?

  1. History, because an unrelated event occurred during the study
  2. Statistical regression, because extreme scores tend to move towards the mean
  3. Instrument decay, because the test may have become easier over time
  4. Self-selection, because motivated students may have chosen the tutorial Correct answer.

Explanation

When participants choose their own condition, pre-existing differences such as motivation or prior achievement are confounded with the treatment, which is the self-selection threat. History, instrument decay, and regression are genuine validity threats but none of them arises specifically from voluntary assignment. Only self-selection directly explains why the groups may differ before the treatment begins.

Question 36Paper-I

A test of numerical ability reports a Cronbach's alpha of 0.91. Which interpretation is most defensible?

  1. The test is valid for predicting success in all postgraduate programmes
  2. The test has high test-retest stability across repeated administrations
  3. The test scores show high internal consistency among the items Correct answer.
  4. The test measures numerical ability accurately for every individual candidate

Explanation

Cronbach's alpha is an index of internal consistency, estimating how uniformly the items measure a single construct; 0.91 indicates high homogeneity. It says nothing about individual accuracy, predictive validity, or temporal stability. Stability over time is estimated by test-retest reliability, which requires repeated administrations.

Question 37Paper-I

A researcher wishes to test whether the proportion of first-generation learners differs across four faculties. Which statistical test is most appropriate?

  1. Pearson product-moment correlation
  2. Paired-samples t-test
  3. One-way analysis of variance
  4. Chi-square test of independence Correct answer.

Explanation

The chi-square test of independence examines association between two categorical variables, here faculty and first-generation status. ANOVA and the t-test compare means of continuous dependent variables, and correlation assesses linear association between continuous variables. Since both variables are categorical, only the chi-square test fits.

Question 38Paper-I

A student reads an article claiming that 'students who sleep less score higher' and concludes that reducing sleep will raise marks. Which reasoning error is the student making?

  1. Confusing correlation with causation Correct answer.
  2. Committing the fallacy of composition
  3. Confusing a sample with a population
  4. Committing the appeal to authority

Explanation

A correlational finding does not establish that one variable produces the other; a third factor such as workload could raise study hours while reducing sleep. Treating an association as a causal instruction is the classic correlation-causation error. The other fallacies concern parts and wholes, sampling generalisation, and reliance on prestige, none of which is described.

Question 39Paper-I

Given the series 3, 7, 15, 31, 63, what should come next?

  1. 95
  2. 111
  3. 129
  4. 127 Correct answer.

Explanation

Each term equals twice the previous term plus one: 3x2+1=7, 7x2+1=15, and so on, so the next term is 63x2+1=127. Equivalently, the differences double each time (4, 8, 16, 32, 64). Applying either rule yields 127, and the other options do not fit the pattern.

Question 40Paper-I

A university wants to compare the teaching effectiveness of four methods while controlling for the effect of students' prior achievement. Which design is most suitable?

  1. Static-group comparison design
  2. One-group pre-test post-test design
  3. Analysis of covariance with prior achievement as covariate Correct answer.
  4. Post-test-only design with random assignment

Explanation

Analysis of covariance statistically adjusts group means for a continuous covariate such as prior achievement, thereby increasing precision and controlling a source of variance. A post-test-only design ignores prior achievement, the one-group design lacks a comparison group, and the static-group design lacks random assignment. Only ANCOVA explicitly controls the named variable.

Question 41Paper-I

In a 2x3 factorial experiment, how many independent variables and how many treatment conditions are involved?

  1. Six independent variables and two treatment conditions
  2. Three independent variables and two treatment conditions
  3. Two independent variables and six treatment conditions Correct answer.
  4. Two independent variables and five treatment conditions

Explanation

In factorial notation, each number denotes an independent variable and its number of levels; a 2x3 design therefore has two factors with two and three levels respectively. The number of cells, or treatment conditions, is the product 2x3=6. Summing the levels instead of multiplying them is a common error.

Question 42Paper-I

A teacher wants learners to evaluate competing explanations for a social problem and defend a position with evidence. Which assessment task best matches this objective?

  1. A spelling test on technical vocabulary
  2. A multiple-choice quiz on definitions of key terms
  3. A fill-in-the-blank worksheet on chronological dates
  4. A structured debate followed by a written justification Correct answer.

Explanation

Assessment tasks should align with the intended learning outcome; evaluating and defending a position requires learners to weigh evidence and argue, which a debate with written justification elicits. Recall tasks such as quizzes, cloze worksheets, and spelling tests measure memory rather than evaluation. Constructive alignment thus favours the debate task.

Question 43Paper-I

A researcher administers a new attitude scale to the same group twice, two weeks apart, and correlates the two sets of scores. Which property is being estimated?

  1. Inter-rater reliability
  2. Test-retest reliability Correct answer.
  3. Content validity
  4. Construct validity

Explanation

Administering the same instrument on two occasions and correlating the scores estimates test-retest reliability, that is, temporal stability. Inter-rater reliability concerns agreement between scorers, while content and construct validity concern whether the instrument measures the intended attribute. The two-administration procedure is the defining feature of test-retest estimation.

Question 44Paper-I

A researcher wants to measure the 'quality of campus life' but finds that the concept is abstract and has several dimensions. Which step is most essential before constructing the questionnaire?

  1. Choosing a five-point response format for all items
  2. Conducting an operational definition and identifying dimensions and indicators Correct answer.
  3. Selecting a large sample size to increase precision
  4. Deciding on the statistical test for the final analysis

Explanation

Abstract concepts must be operationalised into dimensions and observable indicators before items can be written; otherwise the instrument lacks construct validity. Sample size, response format, and analysis plans are important but presuppose a defined construct. Operationalisation is the logically prior step in measurement.

Question 45Paper-I

In a research report, the section that states how variables were defined and measured, how participants were selected, and how data were analysed is best titled:

  1. Discussion and conclusion
  2. Introduction
  3. Review of related literature
  4. Methodology Correct answer.

Explanation

The methodology section documents the operational definitions, sampling procedure, instruments, and analytic strategy so that the study can be evaluated and replicated. The introduction states the problem, the literature review situates it, and the discussion interprets findings. Procedural detail belongs specifically to methodology.

Question 46Paper-I

Which of the following best illustrates the use of a spreadsheet in developing higher-order thinking rather than mere recall?

  1. Students use formulas to test how changing a subsidy alters a projected budget Correct answer.
  2. Students copy a table of historical dates into a spreadsheet
  3. Students memorise the menu commands for formatting cells
  4. Students print a pre-filled spreadsheet for their files

Explanation

Using formulas to model how one variable affects an outcome engages learners in prediction, hypothesis testing, and analysis, which are higher-order skills. Copying data, printing files, and memorising commands involve reproduction and recall only. The distinguishing feature is manipulation of a model to explore relationships.

Question 47Paper-I

In a communication encounter, a professor's news about a student's failure is delivered in a crowded corridor. Which combination of factors most weakens the effectiveness of this communication?

  1. Empathy and active listening
  2. Encoding and feedback
  3. Semantic barriers and redundancy
  4. Physical noise and an inappropriate channel Correct answer.

Explanation

A crowded corridor introduces physical noise and constitutes an inappropriate channel for sensitive, personal information, both of which reduce fidelity. Encoding and feedback are necessary components rather than weaknesses, and empathy and active listening would improve rather than weaken communication. Semantic barriers and redundancy do not describe the setting.

Question 48Paper-I

A researcher reports: 'the mean score of the experimental group was 78 and that of the control group was 70; the difference was statistically significant at p<0.01'. Which additional information is most necessary before judging the practical importance of the finding?

  1. The gender composition of the two groups
  2. The effect size and confidence interval of the difference Correct answer.
  3. The names of the statistical software used
  4. The number of items in the achievement test

Explanation

Statistical significance indicates that a difference is unlikely to be due to chance, but practical importance depends on the magnitude of the effect and the precision of its estimate, conveyed by effect size and confidence intervals. Software choice and item counts do not speak to magnitude, and group composition concerns generalisability rather than effect size. Reporting effect size alongside p-values is now a standard expectation.

Question 49Paper-I

A researcher tests the same hypothesis on four separate subsamples and reports only the one subsample where p<0.05. Which methodological problem does this illustrate?

  1. Selective reporting and inflated Type I error Correct answer.
  2. Multicollinearity among predictors
  3. Low statistical power
  4. Sampling error arising from small samples

Explanation

Testing the same hypothesis repeatedly and reporting only the significant result is a form of selective reporting or p-hacking; multiple tests inflate the familywise Type I error rate beyond the nominal alpha. Multicollinearity concerns correlated predictors, and low power concerns failure to detect true effects. The problem here is the biased selection of results, not sample size or predictor structure.

Question 50Paper-I

A researcher uses a theoretical framework derived from constructivism while adopting a purely quantitative, hypothesis-testing design. Which criticism of the study's coherence is most defensible?

  1. Quantitative methods can never be used with any theoretical framework
  2. The framework and the design make incompatible assumptions about how knowledge is generated Correct answer.
  3. Constructivism necessarily prohibits the use of statistics
  4. Theoretical frameworks are required only in qualitative research

Explanation

Constructivism typically assumes that knowledge is actively constructed and context-dependent, whereas hypothesis-testing designs assume an objective reality that can be measured independently of the knower. Mixing them without justification creates a paradigmatic inconsistency between ontology, epistemology, and method. The other options overstate the case, since quantitative work can be framed in several traditions and frameworks are relevant to all research.
