Art of Stat: Distributions is an educational app developed by Bernhard Klingenberg. It is available for iPhone users and falls under the category of Education & Reference. This app allows users to explore and visualize both continuous and discrete probability distributions.

With the help of sliders and buttons, users can easily find probabilities or percentiles for computing P-values or when working with discrete distributions. The app also provides the functionality to find critical values for confidence intervals. Additionally, users can display the expected value and standard deviation, and simulate random numbers from various continuous and discrete distributions.

Art of Stat: Distributions is designed for both students and teachers, serving as a valuable tool to visualize and explore probability distributions and their properties. It offers interactive graphics that make learning about probability distributions more engaging and intuitive compared to traditional graphing calculators.

One notable feature of this app is its ability to work offline, making it convenient to use even in airplane mode. The app indicates its offline mode by changing the background color.

The app includes a range of continuous distributions such as Normal, Student's t, Chi-Squared, F, Exponential, Uniform, Gamma, and Beta. It also covers discrete distributions like Binomial, Geometric, Poisson, and even allows users to define their own discrete distribution.

Overall, Art of Stat: Distributions provides a user-friendly and comprehensive platform for exploring probability distributions. Its interactive graphics and offline functionality make it a valuable tool for both students and teachers alike.
