Sometimes it’s easier to learn things by doing as opposed to simply reading about them. That’s the philosophy behind the Statistics Visualizer iPad app, which provides simulations to demonstrate a number of concepts in statistics. Through these simulations, users can explore and learn about different discrete probability distributions (Poisson, geometric, and negative binomial) and continuous probability distributions (normal, student’s t, chi-square, exponential, and Snedecor’s F). For each simulation, users can adjust parameters such as n, the p value, and the left and right bounds of the plot. Each topic also comes equipped with a complementary notes section that is very useful for people with little-to-no knowledge of statistics. If you find yourself wanting even more statistics, you can upgrade to the paid version of the app for additional topics.
