@pocayama2 you are alright. I dont think we need controlled group all the time, and you are right.there are single group or one group design. But controlled group will make the result of our manipulate more clearer .
I am sorry if my english is hard to understand. hehe. I am a student of research and evaluation program from Thailand. :)
Do we really need a controlled group in an experimental research all the time? I have read in one book that there is what we call single group prettest-posttest design.
