Question

Which data set has a variation, or mean absolute deviation, similar to the data

set in the given dot plot?

Answer 1

Add all the absolute

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."

hope this helps
