@jim_thompson5910  can you help me plz?

zarkon · Answer

are you using the median in your definition of absolute deviation

anonymous · Answer

i don't know. it only says this: 

Find the mean absolute deviation of the data. Round to the nearest hundredth if necessary. 

it doesn't say anything about the median.

jim_thompson5910 · Answer

First find the mean

jim_thompson5910 · Answer

You do this by adding up all the numbers and then dividing by 6 (since there are 6 numbers)

anonymous · Answer

yeah? then what do I do?

jim_thompson5910 · Answer

then you subtract each value from the mean (in any order it doesn't matter because we're going to be making each difference positive)

anonymous · Answer

do i only right down one has an answer?

anonymous · Answer

or do i write them all down?

jim_thompson5910 · Answer

what do you mean?

anonymous · Answer

when i subtract the mean from all the values, for an answer to the question do i just put down one value i found or all the values i found?

jim_thompson5910 · Answer

that leads up to the answer, but the differences aren't the answer

anonymous · Answer

oh, ok. then what's the answer?

jim_thompson5910 · Answer

what differences do you get

anonymous · Answer

i get: 

1 2/3, 4 2/3, -5 1/3, 3 2/3, -9 1/3, 4 2/3

jim_thompson5910 · Answer

make each difference positive

so the list becomes

1 2/3, 4 2/3, 5 1/3, 3 2/3, 9 1/3, 4 2/3

Then add up these values

anonymous · Answer

Then i get the answer?

jim_thompson5910 · Answer

not yet

jim_thompson5910 · Answer

what do you get when you add all that up

anonymous · Answer

3.267

jim_thompson5910 · Answer

no, remember that everything is now positive

anonymous · Answer

26 10/3?

jim_thompson5910 · Answer

or 29 and 1/3

jim_thompson5910 · Answer

now divide this result by 6 to get your final answer

anonymous · Answer

THanks man You've been a great help

jim_thompson5910 · Answer

jim_thompson5910 · Answer
