Question

The number of credits being taken by a sample of 13​ full-time college students are listed below. Find the​ mean, median, and mode of the​ data, if possible. If any measure cannot be found or does not represent the center of the​ data, explain why. 8 10 11 11 8 7 7 7 9 7 7 7 8

Answer 1

Mean = 8.23

Median = 8

Mode = 7

Explanation:

Let us arrange the data accordingly:

7 7 7 7 7 7 8 8 8 9 10 11 11

MEAN

The mean is obtained by adding them up and dividing by the 13:

(7 + 7 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 10 + 11 + 11) / 13

= (42 + 24 + 9 + 10 + 22) / 13

= 107 / 13 = 8.23

MEDIAN

This is the number in the middle. There are 13 numbers and so the median will be the 7th.

The median is 8.

MODE

The mode is the number that appears the most.

The mode is 7
