Use & avoid

Use when
A finite evenly spaced set of values is possible and each should be equally likely.
Avoid when
Some values are more common than others.
Support
The evenly spaced values from minimum to maximum using the selected step.
Parameters
Minimum, maximum, and step; every reachable value has equal probability.
Common mistake
Using it when some discrete outcomes are clearly more common than others.
Example
A task can take exactly 2, 4, 6, 8, or 10 minutes with equal likelihood.
