Question

Data Set 1 has a mean of 84 and a MAD of 6. Data Set 2 has a mean of 78 and a MAD of 8.

What can you conclude about the two distributions?

Choose exactly two answers that are correct.

A.
The means-to-MAD ratio is 0.75.

B.
The means-to-MAD ratio is 1.

C.
The distributions are similar.

D.
The distributions are somewhat similar.

Answer 1

ok so first do you know what MAD, and Mean are?

Answer 2

please answer the questions and i will gladly help :)

Answer 3

no

Answer 4

ok so MAD stands for mean absolute deviation do you need me to give you the definition of the two?

Answer 5

Correct! but do you know what the Mad and mean of a problem is and do you know how to find it?

Answer 6

no

Thanks for replying!
Ok so to find your mean you add all your numbers together in your group and divide by however many there are in the group. Example- 5,10,15,20,25 is your group well when you add them your answer will be 75 and since there are 5 numbers in the group you would say 75 divided by 5 and that would give you 15! see how simple it can be! but MAD can get a tad bit tricky
.
So as you know MAD means mean absolute deviation! All you are basically doing is finding mean twice. fist off you have to find the mean of the group then whatever the mean is you take the mean and subtract each number in the group from it... once you do that and find your answers you add them altogether and divide again by however many numbers are in the group! if you need an example i will gladly give one to you! :)
