Ok, I clearly did misunderstand. I thought you were going to select 2 groups to make generalizations about all 3 groups. If you are doing a head-to-head comparison between two of them, your methodology is great. I think it should work out great for you, although non-response can and usually is VERY annoying, but aside from a few tricks which make only little difference, not much you can do. Good luck, and if you need any more help don't hesitate to ask.

Sooo....I am taking ALTA and ONT's 2 professional associations, and then from each prof. association, I am taking 1 simple random sample of members from Alta's prof assoc, and 1 simple random sample from Ont's prof assocation...
(i am choosing a specific prof association b/c it is the same one i am in...i.e. they are, just for e.g., the alta association of accountants and the ont association of accountants).
So, in sum....Redhot25 is choosing 2 associations in total: the Alta assoc. of accountants and the ont association of accountants b/c he has lived/worked in both provinces and they have not been studied in this way before, etc. From the Alta association comes 1 random sample of members, from the Ont association another random sample of members. And ta da, we have my study  ! |
