AB-tests analysis Calculating uplift for AB-test variations

210. Calculating uplift for AB-test variations

When reporting AB-test results we often calculate an uplift in percentage: โ€œThe uplift of AB-test X in activation rate is Y%.โ€

๐Ÿ‘‰ In this exercise calculate an uplift in soft activation rate for longer_onboarding_201803 AB-test.

โš  Submit the integer part of the uplift as the answer. For example, if the uplift is 15.84% submit 15 as the answer.

๐Ÿ’ก Try to write a query that would report an uplift for each variation like so:

...
variation cohort_size soft_activation_rate soft_activation_rate_uplift
control 184 24.44 0
long_onboarding 167 72.31 195.86
