A. Describe how to find the range of
the data set.
B. Find the range.
range is the difference between the least and the greatest values
So, look at the data and do the math.
Thank you Steve. I understand now.
A. To find the range of a data set, you need to determine the difference between the maximum and minimum values in the data set. In this case, we have two columns: one for the months and one for the kilowatt-hours (kWh) or demand watt-hours (DWH) used each month. To find the range of the kWh or DWH used, we should identify the minimum and maximum values of the data set in the appropriate column and then calculate the difference between them.
B. First, let's find the range for the kWh used. Looking at the data, the highest value in the kWh column is 2,640 (in January), and the lowest value is 1,080 (in June). To find the range, subtract the lowest value from the highest value:
Range = Highest value - Lowest value
= 2,640 kWh - 1,080 kWh
= 1,560 kWh
Therefore, the range for the kWh used in this data set is 1,560 kWh.
