Revise: Data collection sourcesA simulation models a situation rather than collecting data directly from it. It can be useful when real-world data would be difficult, costly or time-consuming to obtain. The results describe what happens in the model, so their usefulness depends on how well the model represents the situation.
For a random-number simulation, count the numbers in each range, including both endpoints: 00–22 contains 23 numbers.
Repeated random numbers normally remain valid in a simulation. Do not automatically discard them as you would when selecting different people for a sample.
