Mean Absolute Deviation (MAD)

Mean Absolute Deviation How to find Mean Absolute Deviation (MAD)

Step 1: Identify the numbers in a data set 3, 5, 7, 7, 8

Write the terms in the x column Step 2: Write the terms in the x column

Find the mean of the terms. Step 3: Find the mean of the terms. represents the mean

Step 4: 3 1 1 1 2

Step 5: Find the sum of the terms in last column 3 1 1 1 2

Step 6: Take the sum and divide by the number of terms 8  5 = 1.6 This is the Mean Absolute Deviation

Step 1: Identify the numbers in a data set 83, 95, 87, 87, 78

83, 95, 87, 87, 78
