Question

lesson 4 practice problems
1 which of the dot plots shows a symmetric distribution?
a
b
c
d

Explanation:

Step1: Recall symmetric - distribution concept

A symmetric distribution has a mirror - image on either side of the center.

Step2: Analyze Option A

In Option A, the distribution of dots is symmetric about the value 15 - 16. The number of dots on the left - hand side of the center is approximately equal to the number of dots on the right - hand side in a mirror - like fashion.

Step3: Analyze Option B

Option B is not symmetric as the number of dots on the left and right sides of the center are not mirror - images of each other.

Step4: Analyze Option C

Option C is not symmetric. The pattern of dots on the left and right of the center does not match in a symmetric way.

Step5: Analyze Option D

Option D is not symmetric. The distribution of dots on the left and right of the center is not balanced in a symmetric manner.

Answer:

A.
