Hiya guys, I just have what I'm sure is a simple question about statistics, but I can't seem to find it anywhere ...(adsbygoogle = window.adsbygoogle || []).push({});

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 they took the square root ... if anyone could help, I'd really appreciate it

Thanks so much!
