Art of Stat: Distributions

Modern statistical calculator for teachers and students of statistics.

The Art of Stat: Distributions app explores and visualizes continuous and discrete probability distributions via sliders and buttons.

Don't rely on boring and complicated graphing calculators that don't 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.

Find probabilities or percentiles (two-tailed, upper tail or lower tail) for computing P-values or when working with discrete distributions. Obtain critical values for confidence intervals. Display the expected value and standard deviation, and simulate random numbers.

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