Hi all,
I have data that looks like
number|grouping
I would like to preform stats for each grouping
so
1|5
6|5
10|5
11|5
3|9
5|9
10|9
Say I would like to take the median for above, I should be returned 2 lines,
one for group #5 and one for group #9
Does this make sense?
I am sorry for the basic question, can someone give me the name of a good
book as well?
Thanks,
Lotta
