What is the Random Number Generator?
Generate one or more random integers within a selected range. ITS Research Solution keeps the interactive tool above the explanation so you can calculate first and then review the method used.
Formula or method
Integers are generated in the browser using the Web Crypto API when available.
How to use this tool
Enter the requested values using consistent units, run the calculation and review the main result plus any supporting values. Generate participant-selection numbers from 1 to 1,000 without sending the range to a server.
Interpretation and limitations
For regulated randomization, use an auditable validated system and retain the allocation record. Always check source data, units, rounding and discipline-specific requirements before using a result in assessed, published, regulated or high-stakes work.
