## What is Art of Stat?

News: The Distributions app is now part of the all new "Art of Stat" app, which contains this and seven other modules.

Please consider getting the Art of Stat app for the latest updates and features from the App Store. Simply search for "Ar of Stat" on the App Store. This app will continue to work, but future development is concentrated on the new Art of Stat app.

Original Description:
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.

Continuous Distributions implemented so far: 

- Normal
- Student's t
- Chi-Squared
- F
- Exponential
- Uniform
- Gamma
- Beta

Discrete Distributions:
- Binomial
- Geometric
- Poisson
- Define Your Own Discrete Distribution, or choose from preloaded examples, such as Benford's Distribution of the leading digit

## Key features

- Visualize probability distributions
- Interactive sliders and buttons
- Calculate probabilities and percentiles
- Obtain critical values
- Simulate random numbers
- Offline mode
- Wide range of distributions

### 5/5 — Great App!

*2023-10-20*

This app is awesome. If you need to do a quick calculation to find a probability or find quantile, then this app is for you. My only recommendation is to add a landscape mode for iPad version.

**Developer response:** Thank you for the feedback. Please check out the newest version 2.5.0, now optimized for tablets and landscape mode.

### 5/5 — Top!!!

*2023-06-07, version 2.0.0*

Super einfach, super anschaulich, schnelles bug fixing

### 5/5 — Excellent, simple to use app!

*2023-05-28*

Only request is that the developer adds feature that lets iPad version display in portrait mode (like most of the other Art of Stat apps do)

**Developer response:** Thank you for the feedback. Please check out the newest version 2.5.0, now optimized for tablets and landscape mode.

### 5/5 — Tolle App

*2022-07-19, version 1.9.0*

Übersichtliche Bedienung, gute Funktionen, alle nötigen Verteilungen vorhanden mit ausgezeichneten Graphiken. Sehr empfehlenswert für das Erlernen von Statistik.

### 5/5 — Wonderful App

*2022-06-01*

This is a great app for learning about and working with all kinds of probability distributions. Very intuitive and great graphics. I use it in almost all of my statistics lectures.

### 5/5 — Easy to use, great interface

*2022-03-17*

This app has really brought to life the distributions I work with in statistics. It is the most simple way to visualize distributions I’ve found yet!

### 5/5 — Amazing...super wish I had this in college...

*2021-12-02*

This app brings statistics to life in a way that just can’t be done in textbooks and on whiteboards.

Rather than try to visualize everything in your head, you can manipulate concepts in the app and start to build something that’s so incredibly important: INTUITION...a feeling for the art of statistics.

### 4/5 — Interesting.

*2021-10-18, version 1.6.0*

Interesting and well built in. But it only has 7 distributions.. Would nice to count with other major ones like the Pareto distribution, the log-normal, etc.

### 5/5 — LOVE

*2021-08-21*

Fantastic for my intro stats course, everything I needed in one place. Great graphics and interactively.
