Thanks!
Thank you so much! I was really curious and my AP stats teacher is kind of confused as to what's going on because she hurt herself at the beginning of the year and has been pretty much gone since then, and then refuses to explain why of anything ... I don't think we've actually learned...
Hiya guys, I just have what I'm sure is a simple question about statistics, but I can't seem to find it anywhere ...
I was wondering, when finding the standard deviation of a sample mean, why do you divide the population standard deviation by the square root of n? I'm not really sure why...
