I am working on a 2:1 randomization plan using proc plan. However, I have run into a problem. It is roughly a 2:1 design, but is not even. The study calls for one group to have 45 subjects and the other 21 subjects. Is there a way to do this using proc plan?
ANOVA, or Analysis Of Variance, is used to compare the averages or means of two or more populations to better understand how they differ. Watch this tutorial for more.
