What is a cohort analysis?

Cohort analysis is indeed a method of analyzing the behavior and performance of groups of users over time. By grouping users based on shared characteristics or experiences—such as the month they signed up for a service—analysts can track how these groups behave in relation to certain metrics, such as retention rates or purchase behavior. This allows businesses to gain insights into customer behavior over time, identify trends, and make informed decisions based on the observed patterns within specific cohorts.

In contrast, the other responses pertain to different methodologies or tools: the financial analysis tool for budgeting focuses on forecasting and managing financial resources; the statistical method for forecasting sales is centered on predicting future sales trends through various models; and the data collection technique for surveys deals with gathering information from respondents rather than analyzing user behavior over time. Each of these focuses on distinct aspects of data analysis or financial management, distinguishing them from the specific longitudinal insights derived from cohort analysis.
