first find mean of that data
Nnesha
  • Nnesha
mean = average
Asad786
  • Asad786
MEAN IS ALL ADDED THEN DIVIDED BY HOW MANY NUMERS THERE ARE RIGHT srry about caps

yes right.

first) find the mean 2nd) find distance from the mean and each value 3rd) find the mean of distance data :=)
Nnesha
  • Nnesha
ok
Asad786
  • Asad786
mean is 12.75
Nnesha
  • Nnesha
yes right now find distance between mean and data subtract mean from each value of the data like 12.75 - 4 12.75 - 18

@Hero
Asad786
  • Asad786
oh ok
Asad786
  • Asad786
4=8.75
Asad786
  • Asad786
18=-25
Asad786
  • Asad786
-5.25
Nnesha
  • Nnesha
each distance is an absolute mean deviation \[\rm \left| distance = mean ~deviation \right| = always ~positive \] so \[\left| 12.75-18 \right|= 5.25\]
Asad786
  • Asad786
oh
Asad786
  • Asad786
/12.75-13=.25
Asad786
  • Asad786
right
Nnesha
  • Nnesha
so you can't have the negative sign so 12.75 - 4= `8.75` 12.75 - 18 = `5.25`
Nnesha
  • Nnesha
yes right !
Asad786
  • Asad786
ok
Asad786
  • Asad786
what do i do after
Nnesha
  • Nnesha
find the distance between all points 12.75-16= ? 12.75- 8= ?
Nnesha
  • Nnesha
12.75-11=?
Asad786
  • Asad786
16=3.25
Asad786
  • Asad786
8=4.75
Asad786
  • Asad786
11=1.75
Nnesha
  • Nnesha
yes right now find the mean of distance points `8.75 , 5.25 , .25, 3.25 , 4.75, 3.25, 3.25 ,1.75`

\(\color{blue}{\text{Originally Posted by}}\) @Asad786 MEAN IS ALL ADDED THEN DIVIDED BY HOW MANY NUMERS THERE ARE RIGHT srry about caps \(\color{blue}{\text{End of Quote}}\) ^^that's how we should find mean :=)
Asad786
  • Asad786
lol can i have medal too
Nnesha
  • Nnesha
MEAN IS ALL ADDED THEN DIVIDED BY `HOW MANY NUMERS THERE ARE `RIGHT
Nnesha
  • Nnesha
divide by the number of numbers 30.5 isn't the answer
Asad786
  • Asad786
oh so what is
Asad786
  • Asad786
oh yeah forgot
Asad786
