Answer 1

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!

Answer 2

was that any help?
