answer^

Answer 3

what

Answer 4

7

Answer 5

take each number on your data set and subtract the mean from it....and even if it is negative, mark it positive
4 - 7 = 3
4 - 7 = 3
4 - 7 = 3
5 - 7 = 2
8 - 7 = 1
9 - 7 = 2
9 - 7 = 2
9 - 7 = 2
9 - 7 = 2
9 - 7 = 2

now find the mean of that
(3 + 3 + 3 + 2 + 1 + 2 + 2 + 2 + 2 + 2) / 10 = your answer

Answer 12

first we find the mean of the original data
(0 + 1 + 1 + 2 + 5 + 9) / 6 = 18/6 = 3

now subtract the mean from every number in the data set...making the answer positive
0 - 3 = 3
1 - 3 = 2
1 - 3 = 2
2 - 3 = 1
5 - 3 = 2
9 - 3 = 6

now find the mean of those numbers
(3 + 2 + 2 + 1 + 2 + 6)/6 = 16/6 = 2.6666 rounds to 2.7
its B
questions ?

Answer 13

okay one more

Answer 14

I am ready :)

Answer 15

Four friends played mini golf. Their scores were –3, –2, –1, and 2.

What is the mean absolute deviation of their scores?

Answer 16

I think its 1.5

Answer 17

what do you think

Answer 18

(-3 -2 -1 + 2) / 4 = (-6 + 2)/4 = -1

now subtract mean from data set....making answers positive
-3 - (-1) = -3 + 1 = 2
-2 - (-1) = -2 + 1 = 1
-1 - (-1) = -1 + 1 = 0
2 - (-1) = 2 + 1 = 3

(2 + 1 + 0 + 3) / 4 = 6/4 = 1.5
I think it is 1.5...but not 100% sure....the negatives are kinda throwing me off
