Answer 4

Average, you just add all of them and divide by how many there are.

Answer 5

i did that

Answer 6

i got 7

Answer 7

Step #1 - Find the Average.
Step #2 - Find the Absolute Deviation for each number in the data. Just, how far is it from the Mean?

Answer 8

but i thought the first step was to do the mean

Answer 9

I'm not that sure. I just got up. Tkhunny can help you on this.

Answer 10

Do you need the second step?

Answer 11

Okay, thanks anyway @jabez177

Answer 12

yes i do @Black_ninja123

Answer 13

It is. Mean = Average

If you want the MAD, you need step #2.

Answer 14

You can tag me in a different question. This is a bit too extreme for me.

Answer 15

kk

Answer 16

but i dont know the second step

Answer 17

Find the absolute value of the differences between each value in the data set and the mean.

Answer 18

i got 7 there is no data table or anything :(

Answer 19

Yes you do. How far does each entry deviate from the mean?

|5-7| = 2
|12-7| = 5
etc...

Do all 5.

Answer 20

Use these numbers
{5, 12, 1, 6, 11

Answer 21

oh so you subtract them with one another.

Answer 22

No subtract them with 7

Answer 23

Each one with the Mean. Absolute values only.

Answer 24

5-7
12-7
1-7
6-7
11-7

Answer 25

1 - 7 = -6
6- 7 = -1
11 - 7 = 4

Answer 26

You seem to be missing the absolute values. This is a MAD, not just a MD.

Answer 27

change the negative sign into a positive sign

Answer 28

1 - 7 = 6 ,6- 7 = 1, 11 - 7 = 4

Answer 29
