You ask six students how many courses they are currently enrolled in and we get the results shown below:
4
5

6

Based on this information, calculate the mean deviation. Show your work.
67, on average, students deviate from the mean number of courses by .67 courses.
The values add to 30 and because N = 6, the mean is 5. If we subtract the mean from each value, we find:
4 – 5 = –1
5 – 5 = 0
4 – 5 = –1
6 – 5 = 1
5 – 5 = 0
6 – 5 = 1
Sum = 0
