These are the steps necessary to calculate the MAD of a data set.
What is Step 1: calculate the mean of the data set.
Step 2: calculate the difference between each number in the data set and the mean.

True or false: the following intervals would be appropriate to use for a histogram: 0-4, 5-9, 10-14, 15-20, 30-34
What is false: 15-20 is bigger than the rest of the intervals (they all have to be the same size) and there should be no gaps (to correct: change 15-20 to 15-19 and add the intervals 20-24 & 25-29).
