@freckles

OpenStudy (narissa):

i got 0 percent yesterday so i need help

OpenStudy (narissa):

someone tell me what to add please

OpenStudy (narissa):

ooops man i closed it oh wow

OpenStudy (freckles):

means to mad ratio of that data set 2 thingy it is just wanting you to divide the means number by the mads number

OpenStudy (narissa):

i divide 4.3 and 1 and then 4.9 by 1.2?

OpenStudy (narissa):

or do i add them first?

OpenStudy (narissa):

is it .73 do u put 4.3/1divided by 4.9/1.2

@jim_thompson5910

jimthompson5910 (jim_thompson5910):

I'm not sure, but I'm thinking it over

OpenStudy (narissa):

k thanks i got all wrong yesterday by people saying it was this and this my bad for not seeing how they did it

jimthompson5910 (jim_thompson5910):

does your lesson mention any formulas used to calculate the means-to-MAD ratio?

OpenStudy (narissa):

let me see hold on

OpenStudy (narissa):

OpenStudy (narissa):

do u understand that?

jimthompson5910 (jim_thompson5910):

yes I do. However, I'm not sure why they are subtracting. Can you find another portion of the lesson where it mentions the means-to-MAD ratio?

OpenStudy (narissa):

jimthompson5910 (jim_thompson5910):

ok I see now, thanks

OpenStudy (narissa):

thats all there is i just dont understand

jimthompson5910 (jim_thompson5910):

see attached, specifically the part I'm highlighting in green

jimthompson5910 (jim_thompson5910):

it tells us to divide the difference in the means (positive difference) by the larger MAD value

jimthompson5910 (jim_thompson5910):

difference in means = 4.9 - 4.3 = 0.6 Divide this difference by the larger MAD value (1.2) to get 0.6/1.2 = 0.5

jimthompson5910 (jim_thompson5910):

So the means-to-MAD ratio is 0.5

OpenStudy (narissa):

.5 is the answer

jimthompson5910 (jim_thompson5910):

yes

OpenStudy (narissa):

k im gonna have to look back on here to understand but i have 4 more can u help me? please

jimthompson5910 (jim_thompson5910):

I can, but be sure to post your work/steps done so far. That way I know where to start.
