Question

What is the mean absolute deviation of the following set 3 1 5 5 2 3 2 3 4 2

Answer 1

Answer: 1

Explanation:

3+1+5+5+2+3+2+3+4+2= 30

30/10 =3

3 - 3 =0

3 - 1 = 2

3 - 5 =2

3 - 5 =2

3 - 2 = 1

3 - 3 =0

3 - 2 = 1

3 - 3 = 0

3 - 4 = 1

3 - 2 = 1

0+2+2+2+1+0+1+0+1+1

10/10 is 1

Answer 2

30-3=27

Explanation:

Finding the deviation of this is pretty simple

1) Find the mean

By finding the mean, you add the numbers together, and divide the sum by the number of numbers, in this case there are 10 numbers, so divide by 10

2) Subtract the data value, basically adding all of the numbers up, and subtracting it by 3, the mean.

the number sets:

3,1,5,5,2,3,2,3,4,2

mean=

30/10

by finding this, i added the numbers and divided it by the amount of numbers.

This would equal to 3.

Now, all you have to do is subtract 3 from the data value

The data value is 30, subtracted by 3 would be 27

Sorry if I am wrong, I am just 4th grade :(

I am sure I am right, but in case it IS wrong, use the formula in the explanation :)

I might've gotten it wrong because the numbers were unclear, but I think it is correct:)
