Question

How can you find the Mean Absolute Deviation (MAD) for this set of data?

Answer 1

Add all of the absolute deviations and divide by the number of swimmers.

Explanation:

I just took this exact I-Ready Quiz and got this question correct. :D and

You add all of the absolute deviation numbers together. Then, once you got your sum, you divide your sum by the number of swimmers on the swim team.

1+3+1+0+0+1+0+0+1+1

------------------------------- = 0.8

Answer 2

Answer: Add all the absolute deviations and divide by number of swimmers.

Explanation:

To find the mean absolute deviation of any data we need to follow the following steps:

• Start by finding the mean of the data set.
• Find the absolute value of the difference between each data value and the mean.
• Find the sum of the absolute values of the differences.
• Divide the sum of the absolute values of the differences by the number of data values.

We can see in the picture that it already dome with first two steps so the step after that is " Add all the absolute deviations and divide by number of swimmers."
