1. Nnesha

first find mean of that data

2. Nnesha

mean = average

MEAN IS ALL ADDED THEN DIVIDED BY HOW MANY NUMERS THERE ARE RIGHT srry about caps

4. Nnesha

yes right.

ok 1 sec

6. Nnesha

first) find the mean 2nd) find distance from the mean and each value 3rd) find the mean of distance data :=)

7. Nnesha

ok

mean is 12.75

9. 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

oh ok

4=8.75

18=-25

-5.25

15. Nnesha

each distance is an absolute mean deviation $\rm \left| distance = mean ~deviation \right| = always ~positive$ so $\left| 12.75-18 \right|= 5.25$

oh

/12.75-13=.25

right

19. Nnesha

so you can't have the negative sign so 12.75 - 4= 8.75 12.75 - 18 = 5.25

20. Nnesha

yes right !

ok

what do i do after

23. Nnesha

find the distance between all points 12.75-16= ? 12.75- 8= ?

24. Nnesha

12.75-11=?

16=3.25

8=4.75

11=1.75

28. 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

1 sec

30. Nnesha

ok :=)

30.5

32. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @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 :=)

lol can i have medal too

34. Nnesha

MEAN IS ALL ADDED THEN DIVIDED BY HOW MANY NUMERS THERE ARE RIGHT

35. Nnesha

divide by the number of numbers 30.5 isn't the answer

oh so what is

oh yeah forgot

3.8125

39. Nnesha

looks good ,good job!

thx
