what are the mean median mode and range of the following data set given the altitude of lakes in feet. -11 -28 -17 -25 -28 -39 -6 -46

Answer 1

First, let's order the data set:

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

Mean: To find the mean, we add up all the numbers in the data set and divide by the total number of values.

Mean = (-46 + -39 + -28 + -28 + -25 + -17 + -11 + -6) / 8
Mean = -200 / 8
Mean = -25

Median: To find the median, we need to first order the data set from lowest to highest. In this case, we have already done that. The median is the middle value in the data set. If there are an even number of values, we take the average of the two middle values.

Median = (-28 + -25) / 2
Median = -26.5

Mode: The mode is the value that appears most frequently in the data set. In this case, there is no value that appears more than once, so there is no mode.

Range: To find the range, we subtract the lowest value from the highest value in the data set.

Range = -6 - (-46)
Range = 40

So, the mean is -25, the median is -26.5, there is no mode, and the range is 40.
