This is my question: For the 100 users with the most friends, how much overlap is there in the reviews of these users with the reviews of their friends? (which means: what percentage of the reviews of the friends is about the same business(es) a user has reviewed?)  Make a nice plot to visualize this. The result should be a percentage for the top 100 users with the most friends.   I have two data sets that are given:   review data set with: user_id review_id business_id (multiple observations for one user) review_count user data set with: user_id friends (list of friends separated by ,) number_friends   Can someone please help me, this is a school assignment but I'm stuck. Thank you so much!!    ... View more
