Array statement without the loop is so I don't have to type the list of variables out multiple times, can refer to it as of vars(*).
Also, can refer to them as vars(i).
Arrays in SAS are only a way to alias variables so you can access them with the format vars(i) where is the i'th variable in the array list. Or in summaries like I'm doing.
If you have a new question, post it as a new thread.
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.
