A concise description of the gap between the current and desired business situation, including who is affected and why it matters.
- Research Objective
- Related: Research Question, Success Criteria
A statement of what the analysis is meant to accomplish, expressed with measurable outcomes so that success can later be judged.

A testable, provisional explanation or prediction about the data that the analyst will confirm or reject using evidence.
- Research Scope
- Related: Research Question, Research Plan, Assumption
The boundaries of an analysis, stating which questions, data, time periods, and stakeholders are included and which are explicitly excluded.
- Assumption
- Related: Limitations and Caveats, Research Scope
Something accepted as true for planning purposes without supporting evidence, which must be validated before results are relied upon.
- Root Cause Analysis
- Related: Business Problem Statement, Current State Analysis
A structured method for tracing a visible symptom back to the underlying causes so that analysis targets the real problem rather than its effects.
- Success Criteria
- Related: Research Objective, Key Performance Indicator
Pre-agreed, measurable conditions that define whether the research answered its questions well enough to support a decision.
- Current State Analysis
- Related: Root Cause Analysis, Descriptive Statistics
An examination of how processes, data, and performance work today, providing a baseline against which future changes are compared.
- Research Plan
- Related: Research Scope, Data Source, Sampling
A document describing the questions, data sources, methods, timeline, roles, and deliverables for an analysis effort.
- Primary Data
- Related: Secondary Data, Sampling
Data collected directly from original sources, such as surveys, interviews, or observations, specifically for the question at hand.
- Secondary Data
- Related: Primary Data, Data Source, Data Lineage
Data that already exists because someone else gathered it for another purpose, such as published reports, sales records, or government statistics.
- Data Source
- Related: System of Record, Data Lineage, Data Profiling
Any system, person, document, or repository from which data is obtained, together with its owner and access conditions.
- Data Quality Dimensions
- Related: Data Profiling, Data Cleansing
The characteristics used to judge whether data is fit for use, commonly completeness, accuracy, consistency, timeliness, validity, and uniqueness.
- Data Profiling
- Related: Data Quality Dimensions, Outlier, Data Cleansing
A technique of examining data structure, values, and patterns to reveal gaps, duplicates, invalid entries, and unexpected distributions before analysis begins.
- Data Dictionary
- Related: Data Lineage, Data Source
A reference that defines each data element's meaning, format, allowed values, owner, and source so that terms are used consistently.
- Data Lineage
- Related: Data Dictionary, System of Record
The documented path data travels from origin through transformations to reporting, used to trace errors and demonstrate trustworthiness.
- Population
- Related: Sampling, Inferential Statistics
The complete set of items, people, or transactions about which the analyst wants to draw conclusions.
- Sampling
- Related: Population, Inferential Statistics, Limitations and Caveats
Selecting a subset of a population to analyze when examining everything is impractical, together with the method used to choose that subset.
- Personally Identifiable Information
- Related: Data Source, Data Lineage
Data that can single out an individual, directly or in combination with other data, and therefore requires protection and lawful handling.
- System of Record
- Related: Data Source, Data Lineage
The authoritative source that holds the official, master version of a data element when several systems contain similar values.
- Descriptive Statistics
- Related: Inferential Statistics, Outlier
Summary measures such as totals, averages, percentages, and spread that describe what is in a dataset without generalizing beyond it.
- Inferential Statistics
- Related: Statistical Significance, Sampling, Correlation
Methods that use sample data to estimate population values or test hypotheses, producing confidence intervals and probability-based conclusions.
- Correlation
- Related: Inferential Statistics, Trend Analysis, Statistical Significance
A measured relationship in which two variables move together; on its own it does not show that one causes the other.
- Trend Analysis
- Related: Descriptive Statistics, Segmentation
Comparing values over time to identify the direction, rate, and pattern of change, including seasonality, so future performance can be anticipated.
- Segmentation
- Related: Trend Analysis, Descriptive Statistics, Insight
Dividing a population into meaningful groups sharing characteristics so that patterns and needs hidden in aggregate totals become visible.
- Outlier
- Related: Data Profiling, Descriptive Statistics
A value far from the rest of the observations, which may signal a data error, a rare event, or an important exception worth investigating.
- Statistical Significance
- Related: Inferential Statistics, Hypothesis, Limitations and Caveats
A measure of how unlikely an observed result would be if no real effect existed; it supports but does not prove a conclusion.
- Data Cleansing
- Related: Data Quality Dimensions, Data Profiling
Correcting or removing inaccurate, duplicated, incomplete, or badly formatted records so that analysis rests on reliable input.
- Data Visualization
- Related: Data Storytelling, Descriptive Statistics
Representing data graphically, such as with charts or dashboards, so that patterns are seen faster than through tables alone.
- Data Interpretation
- Related: Finding, Insight, Limitations and Caveats
Explaining what the analysis results mean in business terms, including what changed, by how much, and what that implies.
- Finding
- Related: Insight, Data Interpretation
A factual, evidence-based statement produced by the analysis, stated without judgment or proposed action.
- Insight
- Related: Finding, Actionable Insight, Data Storytelling
A finding connected to context and consequence that explains why something happened and what it means for the business.

- Related: Insight, Data Visualization, Recommendation
Presenting results as a coherent narrative that links evidence, meaning, and recommended action for a specific audience.
- Limitations and Caveats
- Related: Assumption, Data Interpretation, Statistical Significance
The acknowledged weaknesses of an analysis, such as data gaps, assumptions, or sample bias, that bound how far its conclusions can be trusted.
- Recommendation

- Key Performance Indicator
- Related: Success Criteria, Recommendation
A defined, repeatable measure used to track whether a chosen action delivers the intended business outcome over time.
