Do you know the formula for MAD?
Here it is how it looks like:
|dw:1434479283962:dw|
It will be a long process...
Steps:
1. You already find the mean :)
2. Get the difference of the mean from each value
3. Get the sum of each differences
4. Then divide it by the number of the data set.

so difference = subtracting right? but what do i subtract it (19) with?

- anonymous

wait, for the mean are you sure you'll get 19?

- gabbyalicorn

yeppers. :)

- anonymous

what is 16+20+15+11+13 ?

- gabbyalicorn

oh, i got 15

- anonymous

yep :) Now we got the same thing.
Step number two: \(\sf x-x_{mean}\)
For example, you have x= 16 and xmean is 15, so 16-15 is 1.
Do this for x=20, x= 15, x=11 and x=13 and tell me what you get :)

- gabbyalicorn

20 - 15= 5 11- 13= 2

- anonymous

hmm.. given data-mean
so it will be like
16-15 = 1
20-15 = ?
15-15= ?
11-15 =?
13-15 = ?

- gabbyalicorn

oh, i see sorry

- anonymous

no worries :)

- gabbyalicorn

20-15 = 5
15-15= 0
11-15 = 4
13-15 = 2

- anonymous

right, since we are getting the absolute values, we'll ignore the negative differences:)
So far we have the differences: 1, 5, 0, 4, 2
now let's move to step 3:|dw:1434479892954:dw|
Add the values you get from step 2 :)

- gabbyalicorn

11

- anonymous

you forgot to add the difference of 16-15 :)

- gabbyalicorn

oh 12

- anonymous

yes!
now let's go one with the final step. Divide that sum to the number of given data set, which is 5.. so 12/5 is?

- gabbyalicorn

2.4

- anonymous

bingo ;)

- gabbyalicorn

:D
