Identify the means-to-mad ratio of the two data sets, expressed as a decimal.

data set mean mean absolute deviation (mad)
1 4.3 1
2 4.9 1.2

Data set      Mean         MAD
1                    4.3               1
2                    4.9               1.2

The means-to-MAD ratio is simply presenting the Mean and MAD in a fraction form wherein the Mean is the numerator and the MAD is the denominator and simplifying the fraction.

Data Set 1: 4.3/1 = 4.3
Data Set 2: 4.9/1.2 = 4.08
