Question

The number of bagels sold daily for two bakeries is shown in the table.

Bakery A Bakery B
53 34
52 40
50 36
48 38
53 41
47 44
55 40
51 39

Based on these data, is it better to describe the centers of distribution in terms of the mean or the median? Why? Select the correct answer below. (5 points)

Mean for both bakeries because the data is symmetric
Mean for Bakery B because the data is symmetric; Median for Bakery A because the data is not symmetric
Mean for Bakery A because the data is symmetric; Median for Bakery B because the data is not symmetric
Median for both bakeries because the data is not symmetric

Answer 1

“Mean for both bakeries because the data is symmetric.”

Explanation:

This is correct because the numbers shown in this problem is all in the same range. Meaning that on bakery A and B there are no stray numbers, also known as outliers. No outliers means that the data is symmetric. If you search up, you can see that when the data is symmetric, you use “mean.”
