Question

question 1 (1 point) 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: Examine plot a

In plot a, the number of dots on the left and right of the center (around 15 - 16) is approximately the same in a mirror - like fashion.

Step3: Examine plot b

In plot b, the distribution is not symmetric as the left and right sides do not mirror each other.

Step4: Examine plot c

In plot c, the distribution is not symmetric as the left and right sides have different patterns of dot placement.

Step5: Examine plot d

In plot d, the distribution is not symmetric as the left and right sides are not mirror images of each other.

Answer:

A. Plot a
