Retention rate with a likely range
Type a cohort size and how many players came back. Get the retention rate and a likely range that shows how much of a change could be chance.
Before and after baseline
Paste daily players before and after a change. See both averages, the change, and whether it is bigger than the normal day-to-day spread.
Daily players per peak player
Divide one day's daily players by that day's peak concurrent players to see how spread out play is across the day.
