Question

Which factor does the width of the peak of a normal curve depend on?

Answer 1

The answer would be standard deviation.

Answer 2

Answer: The width of the peak depends on the Standard Deviation. The   standard deviation is a measure used to quantify the variation or dispersion in the data set. If the standard deviation is low, this means that the set of data tends to be closer to the mean, then the width of the peak in the normal curve is small, for other part if the standard deviation is big, this means that the variation is big and the data set is more spread, this causes that the width of peak to be larger.
