If videos are in correct order of learning then the playlist is more beneficial for data enthusiast. I hope Emma will do it.

Hey Emma, Quick question: What exactly is the coarseness? Could you give a brief explanation .

A user can see 2 different versions of a page, therefore it is coarser. A page can load 2 different sizes of buttons, therefore it is coarser.

Hi Emma! Thank you for such a helpful video! But what is the best option of randomization unit for the experiment where we compare two ad campaigns (for example, sephora from the previous video)? If our users aren't authorized, should we choose cookie within specific amount of time? or pageviews? given that the driver metric is click thought rate

Hi Emma, Very informative video! Would you have suggestions on how to select randomization units for B2B products like data bricks and slack, which have a many to 1 relationship between users and accounts?

Are page level metrics measured at the user level ex: CTR(user) = (num clicks by user)/(num impressions) or for the population (ex: CTR = sum(clicks)/sum(impressions))?

It's possible to do it both ways. With the first one you'd then take an average across all users to get the population-level metric. Though, only the first approach would fulfil the assumptions of a t-test regarding observations' independence, so that's a better choise.
