Question

Find the Mean Absolute Deviation (MAD) of the following test scores.

Remember, the Mean is just the first step.

Scores:
{ 48, 61, 73, 76, 76, 74 }

Answer 1

Based on the calculation below, the Mean Absolute Deviation (MAD) of the test scores is 0.

How to calculate Mean Absolute Deviation (MAD)

The mean of the 6 test scores is first calculated as follows:

Mean = Sum of the test scores / Number of test scores = (48 + 61 + 73 + 76 + 76 + 74) / 6 = 68

We can now calculate the MAD of the test scores as follows:

MAD = Sum of deviations of all the test scores from the Mean / Number of test scores = ((48 - 68) + (61 – 68) + (73 – 68) + (76 – 68) + (76 – 68) + (74 – 68)) / 6 = 0 / 6 = 0
