Question

Enzo’s mean score is 44. Zahra’s mean score is 38. How much greater is the mean absolute deviation for Zahra's scores than for Enzo's scores?

Answer 1

6.0 is the answer.

Answer 2

6

Explanation:

The first thing we must do is clarify concepts in order to solve the problem.

The absolute mean deviation is the absolute mean distance between each point in the sample, in this case there are only two points, therefore the answer is the difference between these two values, that is:

d = | 44 - 38 |

d = 6

Which means that 6 is the deviation between one score and the other.
