How to use Standard Deviation?
Well, one standard deviation contains about 67% of the population. If you think of a bell curve, a standard deviation is the area under the curve from -1 to 1 of the standard normal bell curve (the standard normal bell curve is centered at zero.) That might not be the answer you’re looking for, though. I think a way you can use the standard deviation is to determine how many boys are in the standard deviation vs. how many girls are in the standard deviation. Better yet, maybe you could find the standard deviation of the boys by themselves and then the standard deviation of the girls by themselves, and whichever group has a higher standard is your winner.
