Answer 3

@amistre64

Answer 4

*is it

Answer 5

I don't believe 0.2 is a ratio?

what did you get as the mean for the first set? :)

Answer 6

17

Answer 7

@jigglypuff314 i got 17 for the first set

Answer 8

that's right :)
do you know how to find the MAD?

Answer 9

umm nope

Answer 10

you basically find the difference between each value and the Mean
so for Set 1
you would get
17 - 14 = 3
18-17 = 1
etc
{3, 1, 4, 2, 0} would be the MAD set, then find the Mean of that :)

Answer 11

okay can stay so you can see if i get something right?

Answer 12

of course :)

Answer 13

the mean of the second one is 18

Answer 14

yes ^_^

Answer 15

so then i subtract

Answer 16

mhmm

Answer 17

15-18=3

Answer 18

you're doing great :)
keep going

Answer 19

17-18=1

Answer 20

yes

Answer 21

3,1,i need some help

Answer 22

{3, 1, 4, 2, 0} is it the same as this ?

Answer 23

not quite
you need to keep going
22 - 18 = 4
20 - 18 = 2
16 - 18 = 2

so {3, 1, 4, 2, 2}

Answer 24

so find the mean then that will be my answer?

Answer 25

the mean it 2.4

Answer 26

@jigglypuff314

Answer 27

that's right :)

Answer 28

so 2.4 is the answer
?

Answer 29

@jigglypuff314

Answer 30

not the answer
it's part of it
ratio
mean : MAD

Answer 31

oh i need to round right?

Answer 32

no, just put 18 as the mean
and 2.4 as the MAD

Answer 33

18:2.4
