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

  1. Set the Minimum (min) and Maximum (max) integer bounds.
  2. Choose the number of random values to draw (up to 100).
  3. 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.
