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

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.
