... so ... What is Cohort Metrics"?

Some definitions:

Metric- well-defined values or sets of values that can be computed for any user registered in Wikimedia projects

Cohort - set of users sharing one or more property or attribute—the time of account creation, for example, or participation in an outreach event or experimental group.

Cohort Metrics help us understand activity and behavior of user groups.

From quality, quantity and type of user contribution, to how well our editors are retained.
