Question

Charlene records the number of pieces of red colored candies in ten bags of candy of assorted colors. find and interpret the mean absolute deviation of the data

6,6,7,7,8,8,10,10,11

Answer 1

To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.

Please see the attached picture for the work.

The mean absolute deviation is approximately 1.48.

This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.
