Average purchase price by cohort

Building on the previous exercise, let's look at the same KPI, average purchase price, and a similar one, median purchase price, within the first 28 days. Additionally, let's look at these metrics not limited to 28 days to compare.

We can calculate these metrics across a set of cohorts and see what differences emerge. This is a useful task as it can help us understand how behaviors vary across cohorts.

Note that in our data the price variable is given in cents.
