Question

13. What is the mean of the data set in the box below? −8, −6, −2, 0, −6, −8, 4, −7, −8, 1 A. −8 C. −6 B. −7 D. −4

Answer 1

Answer: D. -4

Explanation:

-8 + -6 + -2 + 0 + -6 + -8 + 4 + -7 + -8 + 1= - 40

-40 divided by 10= -4

(You're dividing by 10 because there are 10 numbers that you added up)

The mean is -4.

Answer 2

D.)-4
To find the mean you sum up all the numbers then divide by the number of numbers there are
For example there are 10 numbers in this list so you would divide the sum of all of them by 10
-40/10=-4
