Means and proportions

Mean and proportion estimates usually serve as great primary metrics when aligned with the business goals.

The checkout DataFrame is loaded for you, where every row corresponds to a unique user visiting the respective checkout_page along with their actions and additional attributes. A '1' value in the purchased column corresponds to a user purchasing an item, and a '0' means they have abandoned the page without purchasing. You will examine the data and calculate both mean and proportions as an exploratory step towards evaluating which design performs best.
