S2 Week 6 Workshop - logistic regression, hypothesis testing, and A/B testing

The aim of the S2 Week 5 task and the S2 Week 6 workshop is to build your fitness in solving problems about inferential statistics, in particular hypothesis testing, logistic regression and A/B testing.

In the task sheet below, we've given you some exercises to try before the workshop.

We'll release solutions at the beginning of week 6, but we strongly suggest you don't look at them until you've tried the problems for yourself. 

In the workshop:

• If you've done the exercises before the workshop, we suggest that you spend the time in the workshop discussing with other students who've done the exercises if your solutions are right and comparing them with the solutions. As an extension activity we then suggest you look at the report by the Minecraft Speedrunning team and the Discussion on Andrew Gelman's blog. Do you think the official report, or the one commissioned by Dream was more correct?
• If you've not done the exercises before the workshop, we suggest that you spend the time in the workshop with other students who are still working through them.
