Describe social groups in general, and then compare/contrast 3 types of groups as discussed in the course.

So I got the description down. I am trying to do the compare/contrast on friendship, clubs and cooperatives. I wrote down things in the book about each, but not much info on them.

Any ideas on where to look up more info?

I have tried googling 'social groups' and then each term after it. Any other suggestions on what terms I could use?
Thanks!
