Mean Absolute Deviation (MAD) is how far, on average, all data values are from the middle.

To find the MAD, you can follow 3 easy steps:

  1. Find the mean of the values
  2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs which is also the absolute value)
  3. Then find the mean of those distances

For this Math Mini Spark, you’ll be finding the MAD on a spreadsheet.  Follow the steps below.
