Question

mean absolute deviation? what is that? medal and fan anyone who can answer the question first

Answer 1

In statistics, the absolute deviation of an element of a data set is the absolute difference between that element and a given point. Typically the deviation is reckoned from the central value, being construed as some type of average, most often the median or sometimes the mean of the data set.

Answer 2

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!
