What is the median of the numbers shown?

A. 10

B. 13

C. 14

D. 15

E. 16
Arrange the 4 values in ascending order: {4, 10, 16, 26}
Since we have an EVEN number of values, the median will be the average of the 2 middlemost values.

So, the median = (10 + 16)2
= 26/2
= 13

Answer: B

Cheers,

Listing the numbers in ascending order, we have: 4, 10, 16, 26.

Since we have an even number of data values, the median is the average of the two middle values. Thus, the median is (10 + 16)/2 = 26/2 = 13.

Answer: B
