# What is the variance of {15, 4, 2, -7, 8, 10}?

47.9

I'm going to assume you mean population variance (sample variance will differ slightly).

Please differentiate between the two. The first sign says "add the squares of your numbers", the second says "add first, THEN square the sum"

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
