Use the table to answer the question.
The table shows the heights of 5 students in inches. What is the mean absolute deviation for these numbers?
59 71 68 75 67
I don't really understand this that much.
Do you think you can explain it to me more please anyone.

Use the table to answer the question.
The table shows the heights of 5 students in inches. What is the mean absolute deviation for these numbers?
59 71 68 75 67.
I looked up a YouTube Video, and got all the steps to find The Mean Absolute Deviation.
First, You add the 5 given numbers.
59+71+68+75+67=340
Next, You divide the sum you got by adding(340) by how many numbers given (5).
340/5=68
Then, You subtract the quotient (68) by each of the five numbers. (59,71,68,75,67)
59-68=9
71-68=3
68-68=0
75-68=7
67-68=1
All the differences you got by subtracting (9,3,0,7,1) add them together.
9+3+0+7+1=20
Finally, Divide the quotient (20) by how many given numbers there are (5).
20/5=4
Mean Absolute Deviation= 4
We look forward to see more brave and kind students to help out our fellas.
