Re: st: t-test command for simple cross-tabs
Thank you so much for your response. It is my understanding that a
chi-square test can tell me if the relationship between two variable is
significant, lets say region (ne, mw, w, s) and age cateories (19-29,
30-34, 35+). The chi-square refers to whole variables, and the t-test is
based on the categories, such as proportion in a cell (means or
percentages). So, I might want to know if there are significant
differnences in age for those who live in the NE versus the South.
I know of a free software package that calculates my t-tests (STATS), but
I'm not sure how to make STATA do it. I was unable to reach the url
that you indicated, so I am not sure if my email is redundant. If you
have any further comments, I would love to hear them.
