>>I would say mean am I right?

I do not think so. The standard deviation is a measure of dispersion. The mean is a measure of central tendency.

Ok I thought if the standard deviation was too high it would create extremes and the mean would not be resistant. So I see now the variance would increase if the standard dev increases

directrix · Answer

I agree.
