Random Number Generator
Generate pseudo-random integers across any custom minimum and maximum range with statistical summary metrics.
How to Use the Random Number Generator
- Set the Minimum (min) and Maximum (max) integer bounds.
- Choose the number of random values to draw (up to 100).
- Click Generate to produce instant random numbers along with total sum and sample average.
Formulas & Principles
Integer Generation Formula: rand = Math.floor(Math.random() * (max - min + 1)) + min
Sample Mean: x̄ = (∑x_i) / count
Frequently Asked Questions
Are the generated numbers uniformly distributed?
Yes, each integer within the specified range [min, max] has an equal mathematical probability of being selected on every draw.
Are duplicates possible in multi-number generation?
Yes, each draw in this standard generator is independent with replacement.
What algorithm powers the generator?
It uses standard cryptographic-quality pseudo-random floating-point logic scaled via Math.floor(Math.random() * (max - min + 1)) + min.
