How to use Generate a Random Number
- 1. Set the batch size. Enter How many numbers to decide how many values the generator returns in one run, from a single pick to a long list.
- 2. Bound the range. Set Minimum value and Maximum value to define the boundaries every generated number falls within, matching whatever scale your use case calls for.
- 3. Choose a separator. Set Separator to a comma, space or newline so the numbers come out formatted the way you plan to use them.
- 4. Copy the numbers. Copy the resulting list wherever you need it. Rerun the generator any time you want a fresh set of values.
When to use Generate a Random Number
Generate a Random Number gives you one or more numbers within a range you set, a general-purpose alternative to dice, drawing lots, or manually picking a value. It works for anything from a single quick roll to a large batch.
- Settling a decision by drawing a number. A group deciding who goes first or who covers a task wants to draw a random number within a set range and act on the result.
- Generating quick sample data for a demo. Someone building a mock chart or table wants a handful of realistic numeric values to show what the final output will look like.
- Choosing a random page or item to review. A QA tester wants to spot-check a random page number out of a large document rather than always reviewing the same first few pages.
- Running a probability exercise. A student exploring randomness wants to generate a large batch of numbers within a range and check how evenly they spread out.
