Here's how to do it: 

Step 1: find the mean (add all numbers together, divide by how many numbers there are) 

Step 2: subtract each number in the list from this mean 

Step 3: take the absolute value of each number (so they are all positive numbers) 

Step 4: find the mean of these new numbers 

That's the Mean Absolute Deviation!
