Question

which factor does the width of the peak of a normal curve depend on?
a. standard deviation
b. mean
c. median
d. mode

Explanation:

The standard - deviation determines the spread of a normal distribution. A smaller standard - deviation results in a narrower peak, while a larger standard - deviation leads to a wider peak. The mean, median, and mode are all equal in a normal distribution and do not affect the width of the peak.

Answer:

A. standard deviation
