Question

the dotplot below displays the number of math classes taken by a random sample of students at a high school. which of the following is the best description of the shape and center of the dotplot? math classes the distribution of math classes is skewed left with a center around 4 classes. the distribution of math classes is skewed left with a center between 3 and 4 classes. the distribution of math classes is unimodal symmetric with a center around 4 classes. the distribution of math classes is unimodal symmetric with a center between 3 and 4 classes. number of math classes taken

Explanation:

Step1: Analyze the shape

The dot - plot has a single peak at 4 and is symmetric around 4. So it is unimodal symmetric.

Step2: Determine the center

The highest frequency is at 4, so the center is around 4.

Answer:

The distribution of math classes is unimodal symmetric with a center around 4 classes.
