Calculate the Mean Absolute Deviation

Follow these steps to find the MAD for each class’s line plot:

  • List the data for the class vertically.
  • Next to each score, write the distance of that score from the mean.
  • Find the mean of these distances by adding them together and dividing by the number of values.

Hint:

Remember that distances are always positive numbers.
