Hey, while we're being random, I have a question for anyone familiar with statistical hypothesis testing.
When do you use a t-score? In two out of the three stats classes I've taken, my professors taught me to use t-scores when:
a) a degree(s) of freedom is (are) imposed on the null hypothesis
-and/or-
b) the sample size is 30 units or less
My market research professor insists that you only use a t-score, as opposed to a z-score, when the population variance is unknown, when I have clearly learned otherwise.
What do you think? _________________

Woah, I've never heard of that before! *bookmarks*
Yeah, I've already tried the Wiki route for t-score. No gold.

I've never seen such a fine job of thread derailment and dodging Saxy's question in all my days on the forum. Congratulations on all of us being the most eclectic bunch of misfits in and outside of the cavern
