Which sample has a large range?

Sample 1: 2, 5, 8, 12, 15

This sample has a large range because the difference between the smallest value (2) and the largest value (15) is 13.

A sample with a large range has a large difference between the largest and smallest values. For example, a sample with values 1, 2, 3, 4, 5 has a range of 4, while a sample with values 1, 2, 3, 4, 100 has a range of 99.
