finding the ratio of the difference in means to the mad\nwhat is the approximate ratio of the difference in means to the mads of the data sets?\nrobin evelyn\nscores 99, 108, 102, 107, 119 125, 137, 138, 145, 145\nmean 107 138\nmad 5.2 5.6\n4\n6\n7\n31
Answer
Explanation:
Step1: Calculate difference in means
$138 - 107=31$
Step2: Calculate average MAD
$\frac{5.2 + 5.6}{2}=\frac{10.8}{2}=5.4$
Step3: Calculate the ratio
$\frac{31}{5.4}\approx 6$
Answer:
