Cohort Analysis
Plain-language definitionComparing groups that share a start date, source, behavior, or other trait over time. Cohorts reveal patterns hidden by overall averages.
Why it matters
Use the term to make a better decision.
In practice, cohort analysis matters when a team needs to connect a technical or creative choice to a visible change in clarity, performance, discovery, or conversion. The useful question is not whether the term sounds sophisticated. It is what decision it helps the team make.
