Question

In her first five basketball games, Sarah scored 2, 5, 10, 15, and 18 points.

What is the mean absolute deviation for this set of scores?

I got 5.2 points. Am I right?

Answer 1

Answer 2

Three steps:

1. Find the mean of all values

2. Find the distance of each value from that mean (subtract the mean from each value, ignore minus signs)

3. Then find the mean of those distances

That too much and thats why I hate math :)

Answer 3

2 + 5 + 10 + 15 + 18 = 50

50 / 5 = 10

2 - 10 = -8
5 - 10 = -5
10 - 10 = 0
15 - 10 = 5
18 - 10 = 8

8 + 5 + 0 + 5 + 8 = 26
0 doesn't count really o-o and you could just take away the -'s

So the MAD Would be 26. LOL
This MAD has way to many steps.......

But this is my first time doing this and I got 5.2 too ! YASSS...I mean, sure I think its 5.2 ;)

Answer 6

26 / 5 = 5.2 so

5.2 is exactly the MAD
