Explore and visualize continuous and discrete probability distributions via sliders and buttons. Find probabilities or percentiles (two-tailed, upper tail or lower tail) for computing P-values or when working with discrete distributions. Find critical values for confidence intervals. Display the expected value and standard deviation, and simulate random numbers from many continuous and discrete distributions.

Developed for both students and teachers as a tool to visualize and explore probability distributions and their properties. Dont rely on boring and complicated graphing calculators that dont deserve their name. Instead, use the interactive graphics that this app provides to learn about probability distributions and visualize results side-by-side with the numerical solutions.

The app works in offline (airplane) mode and indicates this by changing the background color.
