iOS version

Now part of the all-new Art of Stat app, Inference delivers focused statistical inference for proportions and means, with supporting chi-square and ANOVA tests. It operates offline, supports CSV uploads or direct data entry, and follows the no-ads, one-time unlock model within the Art of Stat family. With a solid 4.0 rating from 13 reviews and 1,000+ total downloads (18 in the last 30 days), it’s a dependable tool for students and teachers.

Pros & Cons

Clear, focused tools for inference on proportions and means
Offline mode supports exam environments and on-the-go learning
CSV upload, copy-paste, and sample datasets simplify data entry
Visualizes confidence intervals and P-values alongside standard errors and test statistics

Narrow focus on inference topics may miss broader statistics subjects (e.g., extensive regression or AI-based analyses) offered by larger suites
Users seeking more guided tutorials or deeper conceptual explanations may find the coverage limited
Unlocking all modules requires a one-time fee, which may deter users looking for a fully free experience

Description

**********
News: The Inference app is now part of the all new "Art of Stat" app, a single app that contains Inference and seven other modules (Explore Data, Distributions, Concepts, Regression, Machine Learning, Resampling and Data Editor).
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.
*********

The Art of Stat: Inference app provides access to the following modules:

- Inference for Proportions (one and two independent samples, McNemar's test for dependent samples)
- Inference for Means (one and two independent samples, Paired t-test for dependent samples)
- Chi-square Test (Independence/Homogeneity and Goodness of Fit)
- One-way ANOVA for comparing several means

No Ads. No Subscriptions. Unlock all modules for a one-time small fee.

Entering your own data is easy:
If you just have a few observations (or if you have the summary statistics), simply type them in. For larger datasets, upload a CSV file of your raw data to a cloud account (such as iCloud or Google Drive) or simply email the file to yourself. Then, open the CSV file in the app and select the variables for your analysis. You can also simply copy & paste raw data from a spreadsheet app (Such as Numbers on iOS or Google sheets). Sample datasets are provided.

The results are stunning:
The app provides relevant plots (side-by-side or stacked bar charts, boxplots, histograms) and computes and visualizes confidence intervals and P-values for testing hypotheses. All relevant information (such as standard errors, margin of errors, z or t scores and degrees of freedom) are clearly displayed and labeled. The P-value is visualized on a graph for the normal, t-, or Chi-Squared distribution.

Developed for both students and teachers as a handy tool for carrying out basic statistical inference and visualize results on the fly.

The app works in on- and offline mode (the app indicates that it is in offline mode with a large green banner), which makes it suitable for exams.

The app also has dedicated modules for exploring concepts such as the coverage probability for confidence intervals or the concepts of Type I & II errors and power. It can actually find the Type II error and power for tests of proportions (and certain tests for means.)
