Answer 3

a good criterion is to compute the mean-to-MAD ratio for each distribution

Answer 4

Answer 5

i checked

Answer 6

we need of a quantitative criterion in order to make a choice

Answer 7

i will tag u when done :)

Answer 12

ok!

Answer 13

I got both mean-to-MAD ratios

Answer 14

i am nearly done :)

Answer 15

i got c

Answer 16

how did u get ur answer @Michele_Laino ??

Answer 17

type 1 was 6.4 and type 2 was 4

Answer 18

when i did mine

Answer 19

distribution 1:
mean = 50, MAD = 4.8

distribution 2:
mean = 62, MAD = 4

Answer 20

i got the same as u, except i got 6.4 for type 1's MAD

Answer 21

i will calculate again and see if u r right :)

Answer 22

i got 6.4, i do not know how u got 4.8

Answer 23

6.4 is correct

Answer 24

hello hello hello hello hello, anyone there, HELLO

Answer 36

okay, here goes nothing, i will press the button now, wish me luck!

Answer 37

I think that 50/6.4 is rather different from 62/4

Answer 38

now u tell me! i got a 20%

Answer 39

epic fail

Answer 40

i have to do it again, and this time, with different questions
