Pair the sites from the table above, then make a table of the differences found by subtracting the smaller percentage from the larger for each category.

For example, using sites A and B, the differences are:
(30% – 10%), (20% – 5%), (10% – 0%), (40% – 10%), and (45% – 30%).
The total of these differences is 20% + 15% + 10% + 30% + 15%, or 90%
