Can I generate reproducible samples with this tool?

Yes, the tool offers a seeded RNG mode; enabling the seed option and entering a value ensures the same sample is produced each time, and the seed can be included in the share URL for reproducibility.

What do the alpha and beta parameters control in the beta distribution?

Alpha and beta shape the distribution’s skewness and concentration: when both are less than 1 the density is U-shaped near 0 and 1, when alpha is greater than beta the distribution skews right, and when beta is greater it skews left; large values of both parameters concentrate mass around the mean.

How can I export or share the results from the Beta Distribution Calculator?

Results can be copied as text, downloaded as CSV or JSON files, or exported as a PNG image of the chart; a share URL can also be generated that includes the current parameter settings and seed.

Is any personal information required to use this calculator?

No personal information is needed; the tool runs fully in-browser and is free to use without account creation.
