Question

1. which dot plot shows a symmetric distribution? 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

It does not have a clear mirror - image on both sides of a central value.

Step3: Analyze Option B

It does not have a perfect mirror - image on both sides of a central value.

Step4: Analyze Option C

If we consider the center around 7, the distribution of dots on the left side (1 - 6) and the right side (8 - 12) is not symmetric.

Step5: Analyze Option D

If we consider the center around 1.65, the number of dots on the left side (1.1 - 1.5) and the right side (1.7 - 1.9) is symmetric.

Answer:

D
