Answer 2

this one i dont know how to start

Answer 3

53

Answer 4

r u sure?

Answer 5

yes, this is a TRICK question

Answer 6

can u tell me how u got it someone helped me yesterday said they knew how to do it and i got 0 percent

Answer 7

what do u mean

Answer 8

what is the mean of data set 1?

Answer 9

is that the middle number?

Answer 10

you add up the numbers and then divide by 5

Answer 11

53

Answer 12

close but that's not the mean for data set 1

Answer 13

huh oops its 55

Answer 14

the second is 52.67

Answer 15

then what do i do

Answer 16

52.67 is not the mean for data set 2

Answer 17

oh gosh its 67

Answer 18

closer

Answer 19

but not quite

Answer 20

it comes to 335 and divide by 5 is 67

Answer 21

more like 338/5 = ??

Answer 22

oh wait, I made a typo

Answer 23

yeah 67, nvm

Answer 24

i was confused

Answer 25

now find the mean absolute deviation (MAD) for each data set

Answer 26

is that the biggest number

Answer 27

do you know how to calculate the MAD?

Answer 28

im confused

Answer 29

so far i have 55 and 57 then i divide that by what?

Answer 30

I'll show you how to do the mean absolute deviation (MAD) for data set 1

Answer 31

k

Answer 32

Data Set 1: {43, 42, 56, 62, 72}


mean = 55 (calculated earlier)


Subtract the mean (55) from each data value in data set 1. Apply absolute value brackets to ensure the result is never negative.


|43 - 55| = 12


|42 - 55| = 13


|56 - 55| = 1


|62 - 55| = 7


|72 - 55| = 17


The results from above are: 12, 13, 1, 7, 17


Add up the results


12 + 13 + 1 + 7 + 17 = 50


And divide that sum by 5 (since there are 5 data values in data set 1)


50/5 = 10


So for data set 1, Mean Absolute Deviation = 10

Answer 33

I'll let you calculate the Mean Absolute Deviation for data set 2

Answer 34

k some of them being subtracted from 67 would be a negative is that right?

Answer 35

but the absolute value bars make the result positive

Answer 36

so that explains the "absolute" in Mean Absolute Deviation

Answer 37

k well i got 9,10,14,16,3

Answer 38

add those up, then divide by 5

Answer 39

52 divided by 5=10.4

Answer 40

then what do i do with those 2 numbers

Answer 41

So we have this summary data

Data set 1: mean = 55, MAD = 10
Data set 2: mean = 67, MAD = 10.4

Answer 42

subtract the means (larger - smaller)

then divide that difference by the larger MAD

Answer 43

yaaa! i did it right oh wow lol thank u

Answer 44

np

Answer 45

.4 divided 10.4

Answer 46

.03

Answer 47

no, you subtract the means (not the MADs)

Answer 48

ok so its 1.15

Answer 49

67-55=12 then 12 divided by 10.4 is 1.15

Answer 50

I'm getting 1.153846154, so yes that's correct

Answer 51

to the nearest tenth

Answer 52

or is it 1.2

Answer 53

yep 1.2 after rounding

Answer 54

thanks man ur alot of help do u have time to help me with 3 more?

Answer 55

i tagged u i just need u to tell me if im right please
