Question

Find the mean, median, and mode of the data set. Round to the nearest tenth. Show work.

2, 10, 6, 9, 1, 15, 11, 10, 15, 13, 15

A. Mean = 8.9
Median = 10
Mode = 15

B. Mean = 8.9
Median = 10
Mode = 8

C. Mean = 9.7
Median = 10
Mode = 15

D. Mean = 9.7
Median = 8
Mode = 15

Answer 1

Answer: C

Explanation:

Mean: (sum of numbers)/(amount of numbers)=mean

2+10+6+9+1+15+11+10+15+13+15=107

107/11=9.7272727

9.7272727 to the nearest tenth is: 9.7

Median: middle numbers of a data set (list from least to greatest)

1, 2, 6, 9, 10, 10, 11, 13, 15, 15, 15

Middle number: 10

Mode: number that appears most in a data set

1-once

2-once

6-once

9-once

10-twice

11-once

13-once

15-three times

Repeated most: 15
