And then the best answer would be:

Each interval should contain 5 values. To determine this, I looked at the lowest number and the highest number to determine the range of numbers that need to be represented. The values are from 1-29, so you would count in groups of 5 numbers. 1-5, 6-10, 11-15, 16-20, 21-25, and 26-30.
All you do is add 3.0 and 2.5
This would give u 5.5
Correct me if i'm wrong, but i hope it helps
