The range is the difference of the greatest value of the data points and the least value. So, for Paula's data, the range is: 16 min*60s/min - 20 s = 940 s. For Kate, the range is: 16min*60s/min - 20s = 940 s. For Sam, the range is: 16min*60s/1min - 10 s = 950 s. If you want to find the overall range, find the greatest and least amount in all of the data given. The overall range is: 16min*60s/min - 10 s = 950 seconds.
