How does the mean absolute deviation (MAD) of the data set 2 compare to the mean absolute deviation of data in set 1? Set 1: 16,15,10,12
Set2: 16,62,15,10,12

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
