Question 10 • MO-Psychology

Which of the following statements about a normal distribution is not true?

Answer
A
A normal distribution is represented by a bell-shaped curve.
B
A normal distribution has the same value for the mean, median, and mode.
C
A normal distribution displays the highest data scores in the middle of the distribution.
D
A normal distribution demonstrates how data scores rise and fall within a sample.

Explanation

A normal distribution is bell-shaped, and its mean, median, and mode are equal. The middle of the curve has the greatest frequency of scores, not the highest data scores; the largest scores are toward the right end. So the statement that the highest data scores are in the middle is not true.
