Question

1. which of the dot plots shows a symmetric distribution?

Explanation:

Step1: Recall symmetric - distribution definition

A symmetric distribution has a shape such that one - half of the distribution is a mirror image of the other half.

Step2: Examine dot - plot A

In dot - plot A, the number of dots on the left side of the center (around 15) is approximately equal to the number of dots on the right side of the center. The pattern of dots on the left mirrors the pattern on the right.

Step3: Examine dot - plot B

In dot - plot B, the distribution is not symmetric. The number of dots on the left and right sides of the center are not balanced in a mirror - like fashion.

Step4: Examine dot - plot C

In dot - plot C, the distribution is not symmetric. The pattern of dots on the left and right sides of the center does not match.

Step5: Examine dot - plot D

In dot - plot D, the distribution is not symmetric. The number of dots on the left and right sides of the center is not evenly distributed in a symmetric way.

Answer:

A.
