Question

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

standard deviation

mean

median

mode

Answer 1

The mean identifies the position of the center and the standard deviation determines the height and width of the bell.

Explanation:

The normal curve is described by a bell curved graph. The bell curved graph of a normal distribution depends on two factors: the mean and the standard deviation. Therefore, the factor that the width of the peak of the normal curve depends on is the standard deviation.

Answer 2

The normal curve is described by a bell curved graph. The bell curved graph of a normal distribution depends on two factors: the mean and the standard deviation. The mean identifies the position of the center and the standard deviation determines the height and width of the bell. Therefore, the factor that the width of the peak of the normal curve depends on is the standard deviation.
