Related: Proportionality, Situational judgment
Active voice

A sentence pattern in which the subject performs the action, as in 'The agent filed the report,' which usually reads more directly than the passive form.

Related: Conciseness, Tone
Parallel structure

Using the same grammatical form for items in a list or comparison so the ideas read as balanced and the sentence is easy to follow.

Related: Conciseness, Topic sentence
Dangling modifier

A descriptive phrase that does not clearly attach to the word it is meant to describe, often producing an unintended or absurd meaning.

Related: Ambiguous pronoun reference, Parallel structure
Ambiguous pronoun reference

The unclear case in which a pronoun such as 'it,' 'they,' or 'this' could point to more than one earlier noun, forcing the reader to guess.

Related: Dangling modifier, Conciseness
Comma splice

Joining two complete sentences with only a comma; the fix is a period, a semicolon, or a conjunction plus any needed punctuation.

Related: Active voice, Topic sentence
Topic sentence

The sentence that states a paragraph's main point and signals what the remaining sentences will explain, support, or illustrate.

Related: Parallel structure, Conciseness
Conciseness

Expressing an idea in the fewest words that keep the meaning intact, cutting filler, repetition, and unnecessary qualifiers.

Related: Active voice, Topic sentence
Tone

The attitude a piece of writing conveys toward its subject and its reader, which should suit the audience and purpose.

Related: Active voice, Conciseness
Premise

A stated reason or piece of evidence offered in support of a conclusion; premises are what an argument asks you to accept before the conclusion can follow.

Related: Conclusion, Assumption
Conclusion

The claim an argument is trying to establish; it is the statement that the premises are offered to support and that should follow from them.

Related: Premise, Inference
Assumption

An unstated belief that must hold for an argument's premises to support its conclusion; if the assumption fails, the reasoning collapses.

Related: Premise, Necessary condition
Inference

A conclusion drawn from evidence rather than stated outright, which should follow necessarily or with high probability from what is given.

Related: Conclusion, Assumption
Necessary condition

A circumstance that must be present for something to occur, though it may not be enough on its own, as oxygen is necessary for fire.

Related: Sufficient condition, Assumption
Sufficient condition

A circumstance whose presence is enough to guarantee an outcome, even though other routes to the same outcome may also exist.

Related: Necessary condition, Logical fallacy
Correlation versus causation

The distinction between two things occurring together and one actually producing the other; co-occurrence alone never proves a causal link.

Related: Assumption, Inference
Logical fallacy

A pattern of reasoning that looks persuasive but fails to support its conclusion, such as attacking a person instead of the argument.

Related: Premise, Sufficient condition

The difference between a new value and an original value, divided by the original value and expressed as a percent.

Related: Weighted average, Misleading graph

Related: Median, Weighted average
Margin of error

The range around a survey estimate in which the true value is likely to fall, given sampling variability and the size of the sample.

Related: Outlier, Misleading graph
Data sufficiency

Deciding whether the information supplied is enough to answer a question, without needing to compute the exact numeric answer.

Related: Misleading graph, Median
Misleading graph

A chart whose scale, axis breaks, or truncated baseline exaggerates or hides a difference, distorting what the underlying data actually show.

Related: Percentage change, Data sufficiency
Working memory

The limited mental workspace that holds information briefly while you use it, such as keeping a code in mind while checking a list.

Related: Chunking, Selective attention
Chunking

Grouping separate pieces of information into larger meaningful units so that more can be held in memory at one time.

Related: Working memory, Recall versus recognition
Change blindness

Failing to notice a change in a scene or document because attention was fixed elsewhere or the change occurred during a brief disruption.

Related: Selective attention, Vigilance
Vigilance

Sustained attention kept on a task that requires detecting rare or subtle events; it tends to decline during long, monotonous monitoring.

Related: Working memory, Selective attention
Recall versus recognition
