What is the means-to-MAD ratio of the two data sets, expressed as a decimal to the nearest tenth? Data Set 1: {43, 42, 56, 62, 72} Data Set 2: {76, 57, 81, 51, 70}

2.4
set 1: mean: 55 , MAD : 10
set 2 : mean: 67, MAD : 10.4
Woah!!! the concept is totally new to me. Thanks for asking. It enlarges my knowledge to the field I never known before.
yw
lol
Method: set 1 : find the mean out by (43+42+56+62+72)/5 = 55 find MAD by formula: \(\dfrac{1}{n}\sum_{i=1}^n |x_i-\bar x|\), where \(\bar x\) is the mean above, that is 55 Hence MAD=\(\dfrac{1}{5} [|43-55|+|42-55|+56-55|+|62-55|+|72-55|]=10\) lalalalalala.... I know something new,
Do the same with set 2.
so the answer is 10
I gave you both of them above the method 1) 10 2) 10.4
so the answer is 10.4
thank you
