I have a couple of data points on a large group of high school students:
A: Who their Friends are
B: Strength of Friendship for each friend (out of 5, 5 being best friends and 1 being acquaintances)
C: Grade Point Average for each student
To start, I want to confirm the "popular kids hangs out with other popular kids" phenomenon, I've aggregated the dataset and now I have all student and their friend count. What would be my next step? What kind of model should I be using to confirm the "popular kids" phenomenon. Next, I hypothesize that "high GPA kids hang out with other high GPA kids", which model should I use here?
Apologies if this is an easy question, I'm new to network analysis and not sure where to start.
