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. 4  6  7  7  4  3  3  3  5  3  3  3  4

Answer 1

Mean = 4.23; median = 4; mode = 3

To find the mean, find the sum of all of the data values: 4+6+7+7+4+3+3+3+5+3+3+3+4 = 55

Divide by the number of data values: 55/13 = 4.23

To find the median, order the data from least to greatest:

3,3,3,3,3,3,4,4,4,5,6,7,7

Find the middle value: 4

The mode is the data value that appears most. There are 6 3's, so 3 is the mode.
