Question

Find the mean and the mean absolute deviation (MAD) for each data set.when you get each answer,find it in the answer choices at the bottom and drag it to the appropriate box.not all answers will be used.

Answer 1

Problem #7

We have the next values

12,16,15,11,31

the mean

to calculate the mean we need to add all the values in the set and then divided the result between the number of members in the set in this case we have 5

MAD

To calculate the MAD we can follow these steps

1. finding the mean(average) of the set of numbers

We already do that the mean is 17

2. find the distance of all the numbers from the mean. you can do this using absolute value and subtract the mean of each value of the set

|12-17|=5

|16-17|=1

|15-17|=2

|11-17|= 6

|31-17|=14

3. Find the mean of those numbers.

`\text{MAD}=(5+1+2+6+14)/(5)=5.6`

MEAN =17

MAD = 5.6
