What is the mean absolute deviation of the data set? {12, 10, 10, 8, 6, 7, 7, 12}

The MAD of  {12, 10, 10, 8, 6, 7, 7, 12} is 2.

Step-by-step explanation:

Step 1 : Add all the values Up:

Step 2 : Divide them by the number of items or numbers:

Step 3: Find the absolute deviations:

Step 4: Add all the absolute deviations:

Step 5: Find the mean:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
