Question

(Giving brainilest) For the data set 62, 73,74,75,76, the mean is 72. what is the mean absoulute deviation

Answer 1

C, 4

Explanation:

To find mean absolute deviation we have to find the difference of each data point with the mean of 72

1. |72-62| = 10

2. |72-73|=|-1|=1

3. |72-74| =|-2|=2

4. |72-75|= |-3|= 3

5. |72-76|= |-4| =4

Now we vind the average of these differences by adding them all up and dividing by the number there are:

`(10+1+2+3+4)/(5) = (20)/(5) =4`

C

I hope this helps! :)

Answer 2

C. The mean absolute deviation is 4.

Explanation:

It is asking how far away is the mean from the farthest number. That is what deviation means. 72 is 4 numbers away from both 62 and 76.
