Replacing rating with median
Oh no! The chocolates dataset got corrupted, and the rating column now contains missing values… You don't want to drop the missing values altogether, so you need to replace them with something. Let's try the median of the column! Maybe you'll implement a better way in the future, but for now, it will do.
The chocolates dataset and the DataFrames and Statistics packages have been loaded for you.
