Question

Data Set A has a mean of 67 and Data Set B has a mean of 92. The MAD of each data set is 12. Express the difference in the measures of center as a multiple of the measure of variation. Round your answer to the nearest tenth.

The difference in the means is about...times the MAD.

Answer 1

2.1 times the MAD

Explanation:

Data Set A has a mean of 67

Data Set B has a mean of 92.

The MAD of each data set is 12

Express the difference in the measures of center as a multiple of the measure of variation.

We find the difference of mean and divide by MAD

Data set B-Data set A

MAD

92-67

12

= 2.0833

So, the difference in the means is about 2.1 times the MAD
