Confirming our test results

To begin this chapter, you will confirm that everything ran correctly for an A/B test similar to that shown in the lesson. Like the A/B test in the lesson this one consists of trying to boost consumable sales through making changes to a paywall.

The data from the test is loaded for you as "ab_test_results" and it has already been merged with the relevant demographics data. The checks you will perform will allow you to confidently report any results you uncover.
