Question

Consider the following data set:

20, 22, 31, 37, 39, 40

How would the range be affected if the data point 15 was added to the data set?

Answer 1

+5 Range; The range is now 25

Explanation:

The original range would be calculated by subtracting 20 from 40, giving you 20 as the range. However, with the point 15 added, there would be a new lowest number, making the new range be 40-15, which is 25.
