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=-21.5

Median=-26.5

Mode=-28

Range = - 6 to-46

Step-by-step explanation:

Arranging the numbers given either in ascending or descending order. In this case, I used descending order as follows

-6

-11

-17

-25

-28

-28

-39

-46

Mode is the number that occurs more than others. In this case, only - 28 appears twice hence it is the mode

The mean is given by adding all the numbers and dividing by the frequency.

The sum of numbers will be - 6+-11+-17+-25+-28+-28+-39+-46=-172

Mean=-172/8=-21.5

The median is the number that appears in the middle after arranging the numbers in descending order as above. In this case, two numbers appear in the middle, that is - 25 and - 28 hence median - 25+-28/2=-26.5

The range of numbers id from - 6 to-46 as arranged above
