Probability Distributions

Matthew Bognar

About this app

Compute probabilities and plot the probability mass function for the binomial, geometric, Poisson, hypergeometric, and negative binomial distributions. Compute probabilities, determine percentiles, and plot the probability density function for the normal (Gaussian), t, chi-square, F, exponential, gamma, beta, and log-normal distributions.

Some knowledge of probability distributions is required! If you don't know what a "binomial" distribution is, for example, this application will not be useful to you.

Ratings and reviews

OUTSTANDING app. Both useful and informative. Clean interface takes you to where you need to go immediately. Besides performing the distribution calculations, the app provides formulas and other relevant information about each distribution succinctly. Thank you for providing this app free of charge and without any ads.

I teach statistic class and cannot imagine doing it without this app. So easy and intuitive for students to use. Visuals are really help to understand statistical concepts. Thanks for beautiful and reliable app

App is most useful for us but few changes or few addition in this app then it get wonderful application ...they changes is add the mgf of continuos distributions and Pgf of distributions. And add the recurrence relations in this app then this app is more useful for us...thanks for providing this Best of statistics...
