Question

A.
The means-to-MAD ratio is 3.

B.
The means-to-MAD ratio is 4.

C.
The distributions are somewhat similar.

D.
The distributions are different.

Answer 2

help @tkhunny

Answer 3

i think one of the answers are D

Answer 4

How do you calculate means-to-MAD? Is it 4 or 3?

Answer 5

i know that i am suppose to find the mean

Answer 6

You have both means.

Answer 7

yes i have both of them its just i don't know how to get the answer nor set it up

Answer 8

Struggling with the definition. Is it mentioned in a particular Text Book?

Answer 9

means-to-MAD ratio
a rational expression comparing the absolute value of the difference of two data sets’ means to the larger of the two data sets’ mean absolute deviations (MAD); the ratio’s value indicates how similar the data sets’ distributions are

Answer 10

Well, there you go.

|132-120| = 12

4 > 3

12/4 = 3

Weird. I wonder why that isn't sufficiently conventional to make it easy to find.

To me, the distributions are VERY different.

Answer 11

so D and A is correct ? @tkhunny

Answer 12

That's what I'm thinking. It's not clear to me that we have accomplished a significant result, but there it is.
