HI,   1. I am using SAS 9.2. And the Box plots are not getting generated with the code mentioned. Results has plot. But when I open it just says loading and never loads.   2. What does " whiskers to the last data point within 1.25 times the interquartile range" mean?   Thanks, Archana ... View more

Thanks a lot DanH_sas!   One last question, does mean needs to be plotted or geometric mean?   Thanks for all the help, appreciate it:) ... View more
