Question

What are the mean, median, mode, and range of the data set given the altitude of lakes in feet

-11, -28, -17,-25, -28, -39, 6, and -46?
mean = -25, median=-26.5, mode=-28; range = 40
mean=-25, median=-40, mode=-26.5, range=28
mean = -26.5, median =-25; mode=-28, range = 28
O mean = -26.5, median = -28, mode =-25; range = 40

Answer 1

Mean (Average) = -23.5

Median = -26.5

Mode = -28

Range = 52

Explanation:

Mean is found when adding all numbers and dividing the outcome by the number of numbers, so -

-11 + -28 + -17 + -25 + -28 + -39 + 6 + -46 = -188

-188 ÷ 8 = -23.5

Median is found in the center, and can be found ordered from least to greatest -

-46, -39, -28, -28, -25, -17, -11, 6

last 2 remaining number would be -28 and -25, add those and divide by 2 which gives you -26.5.

The Median would be -26.5

Mode is the number that has repeated itself the most.

-28 repeated itself the most.

The Range is found when the least number is subtracted by the greatest number so -

6 - (-46) = 52
