Divide into groups of three or four students. Each group should survey other students at the same college by asking them to identify their major and gender. You might include other factors, such as employment (none, part-time, full-time) and age (under 21, 21–30, over 30). For each surveyed subject, determine the number of Twitter followers or Facebook friends.

• Does gender appear to have an effect on the number of followers/friends?
• Does major have an effect on the number of followers/friends?
• Does an interaction between gender and major have an effect on the number of followers/friends?
