Both classes have the same center in terms of the distribution since they both have the same mean; however, class B has scores more spread out from the center since it has a larger standard deviation.

This means the scores in class B vary more and they are further away from the mean.

Class A has scores that are more closer to the mean (and more clustered around it) in relation to class B since it has a smaller standard deviation.
