About this app

News Feb. 2026:
The new Art of Stat app includes this Art of Stat: Distributions module and many other modules useful for statistics and data science. Please install the new Art of Stat app now.
However, this legacy version will continue to work
**********************
Original Description:

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.

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 plus several examples, like Benford

Ratings and reviews

Terrible. Most of the distributions including the normal distribution are locked. Basically useless you pay up. Plenty of other google apps do the same thing or better for free. And all the other Art of Stat apps, such as Resampling, do not have even one review! Silly....

Good-looking and clear interface. One point of improvement would be selectable case studies or real life example that give you a sense of the numbers displayed.

Hi the app is good, but I can't purchase it full since it's not showing in my currency. Need help 🙏 Good Job Guys 🔥 Update: Hey guys, managed to solve the issue, also are y'all planning on adding more distributions in this app ?
