Your friend swims on the school team. In her first four races, her times are 34.6, 29.1, 33.5, and 30.9 seconds. Which time listed for her next race would make the range larger?

Answer: You need a value less than 29.1 or greater than 34.6.

The range is the difference between the highest and lowest value. In this case, those numbers are 29.1 and 34.6.

To make a larger range, we simply need to pick a number smaller than 29.1 or larger than 34.6. This will produce a larger difference (or range).
