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
