I am writing a proposal for a study
. I have 3 groups: Group A- receiving specialized intervention technique Group B- receiving regular intervention Group C- control/receiving no intervention
- Group A- receiving specialized intervention technique
- Group B- receiving regular intervention
- Group C- control/receiving no intervention
I want to compare each groupsgroup's mean on a standardized test pre and post intervention to see if the specialized intervention increased means on the standardized test. What statstest do I use?
