What is the mean absolute deviation of the data set?
neonofarm [45]

Answer:

<u>B. 2</u>

To find MAD, find the mean of the set, then find how far each number is from the mean. Next, find the mean of THAT set of numbers. Yea, I know it's a bit confusing... don't worry!

Find the mean of the set:

12 + 10 + 10 + 8 + 6 + 7 + 7 + 12

72

72 / 8

<u>9</u>

Find how far each number is from 9:

12 - 9 = <u>3</u>

10 - 9 = <u>1</u>

10 - 9 = <u>1</u>

9 - 8 = <u>1</u>

9 - 6 = <u>3</u>

9 - 7 = <u>2</u>

9 - 7 = <u>2</u>

12 - 9 = <u>3</u>

Find the mean of that number set:

{3, 1, 1, 1, 3, 2, 2, 3}

3 + 1 + 1 + 1 + 3 + 2 + 2 + 3

16

16 / 8

<u>2</u>

<u>So the answer is 2!</u>

Not so hard after all   :D
