#To find the deviation of each value, subtract all numbers with its mean value.
#To find the deviation of each value, subtract all numbers with its mean value.
#Then find the average deviation, add all the deviation values and divide by the number of given set of numbers.
#Then find the average deviation, add all the deviation values and divide by the total number of given numbers.
