    It is the standard deviation without squaring it. Basically it tells you how spread out from the mean your group of numbers is. 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!
