(With Proof from Four Years of Fundraising Data from Wikipedia)

The Wikipedia fundraising team was performing up to 100 AB tests per week. It wasn’t enough to find the gains they needed. They needed to use statistics to interpret Their AB tests accurately, but also to estimate smallest acceptable sample sizes to increase testing frequency. They were not comfortable trusting methods proposed by other practitioners or academics who could not prove that their methods would work accurately for Wikipedia data.

In this webcast talkZack Exley (Strata bio, Wikipedia) and Sahar Massachi (LinkedIn profile, Strata bio) will present simple methods that we believe accurately predict future performance from AB test results, and that allow them to determine the smallest acceptable sample size.

Using four years of AB testing data, they’ll show that these methods really work. By taking a walk through four years of data, they will show how their current methods would have predicted the actual outcomes of long tests with much smaller samples, and the implications of various decisions about statistical confidence, power, sample size and choice of statistical method.

This webcast session will be useful to anyone who performs AB tests, manages teams that rely on AB testing, or holds responsibility for implementing or maintaining AB testing platforms.
