Varyans experiment comparing different distributions with the same average

About the app

Varyans is an interactive learning lab built to sharpen probability and randomness intuition through five focused experiments.

Each experiment brings an optional estimate, finite simulation, exact theory, and the whole distribution into one comparison flow.

Highlights

  1. 5 interactive experiments

    Five labs explore averages, distributions, randomness, rare-event rates, and short-run noise from different angles.

  2. Theory and simulation

    Exact mathematical theory, the finite result from each run, and the whole distribution appear side by side.

  3. Offline and on device

    Core experiments work without an internet connection, and the latest experiment state stays on the device.
