Hi Everyone!
Hoping that someone can help me out with this.
I am looking to send out a survey to 3 provinces (each of their respective professional associations). I don't have the survey specifically developed yet, but it will be all (or super close to all) quantitative in nature.
My question is how do I determine my sample size? I want to take a simple random sample from each of the 3 (I think that is still called simple random sampling?). Do I take the same number from each one, or do I somehow scale it? 1 org has approx 1600 members, another 1100 or so, and another 5400 or so!
Cruising around online, I have found one site that, depending on which scenario I put in, would sample each province for approx. 365 - 370 or so; or, it would sample the big one for approx 359, and the other two for around 310 and 285 respectively?
I'm looking for a "justifiable" type number...I know things may not be perfect, but something that is workable/passable at the momment.
Thanks for all help...a stats saviour would be truly appreciated 
!!!!
