Question

question 4 points 1

in a normal distribution, there can be _________ mode(s).

two

one

Explanation:

Define normal distribution shape

A normal distribution is a symmetric, bell-shaped probability distribution. Using the Data Distribution Shape concept, we analyze its symmetry and peak structure.

Analyze the peak of the curve

The highest point on the probability density curve of a normal distribution represents the most frequent value. Because the bell curve has exactly one central peak, it is unimodal.

Determine the number of modes

Since the distribution has only one peak, there is exactly one value where the probability density is maximized. Therefore, a normal distribution has exactly one mode.

Answer:

• two
• one (Correct answer)
