Question

Which of the following data sets has the mean, median, and mode as the same number?

A. 10,10,12,12,13,13
B. 2,3,4,4,5,7
C. 4,7,11,11,16,17
D. 1,2,3,3,5,6

Answer 1

C. 4, 7, 11, 11, 16, 17

Explanation:

The mean is the average of the numbers'

The median is the middle number

The mode is the number that occurs most often.

Let's look at each data set I turn.

A. 10, 10, 12, 12, 13, 13

Mean = 11. 7; Median: = 12; Modes: 10, 12, 13

All three measures are different.

B. 2, 3, 4, 4, 5, 7

Mean = 4.2; median = 4; mode = 4

Median and mode are the same, but the mean is different.

C. 4, 7, 11, 11, 16, 17

Mean = 11; median = 11; mode = 11

All three measures are the same.

D. 1, 2, 3, 3, 5, 6

Mean = 3.3; median = 3; mode = 3

Median and mode are the same, but the mean is different.
