What is cohort analysis?
Uniform Group Analysis is also known as time-based cohort analysis. A cohort is a group of respondents who share a common characteristic over a certain period of time.
Cohort analysis is a part of behavioral analytics that examines data from large sets and breaks them down into related groups to parse them to get a better understanding of behaviors, patterns, and trends. These smaller groups—or cohorts—share similar characteristics in a specified time frame.
Larger, undifferentiated datasets may include various programs or groups participating in a study at different time periods. Uniform Group Analysis within the Percept Research reports indicates trends based on the same group of respondents participating in the study during the time period to factor out the influence of new respondents entering during the timeframe as well as respondents not participating consistently during the timeframe.
This allows an apples-to-apples comparison of respondents to better understand trends.
