3-4
% OF DEVIATION
We calculate the % of deviation between the average and high , and the average and low . We
discard any that has a deviation greater than 10% from the average .
% of Deviation Between High (5.5 ft/sec) and Average
% deviation = x 100 = 5.7%
% of Deviation Between Low (4.8 ft/sec) and Average
% deviation = x 100 = 7.7%
Since the no deviation is greater than 10% from the average , all the values are useable.
