Answer:
I did the math, and the answer's not in there.
Step-by-step explanation:
Mean is the average of the data.
-12 + -9 + -14 + -39 + -49 + -49 + -18 + -43 = -233 / 8 = 29.125 = 29.1 is the mean
Median is the value in the middle. You have to arrange the numbers in ascending order first.
-49, -49, -43, -39, -18, -14, -12, -9
Notice, the middle valued are -39 & -18. In this case, get its average.
-39 + -18 = -57 / 2 = -28.5 is the median
Mode is the most frequent number in the data. So the answer is -49.
Range is the difference of largest number to the smallest number. (Take note that we are dealing with negative numbers.)
-9 - -49 = 40
