...I understand why it becomes more and more insignificant as the value of n increases, but what is the purpose of subtracting 1 from n in the sample population in the first place? Also, what is the purpose of squaring the result of x values minus the mean?(adsbygoogle = window.adsbygoogle || []).push({});

I can do the problems. I'm just a bit confused about what each step means and where the numbers are coming from. Any help you could give me would be most appreciated...
