StatPREP Little Apps review
Free browser apps help classes explore statistical ideas through samples and graphics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
StatPREP Little Apps are free, browser-based tools for teaching and learning statistics through data and graphics. The collection is aimed at college instructors teaching statistics with real data and visualization, and it can support class activities as well as learner exploration. Its apps address center and spread, points and densities, confidence and t, resampling, stratification, and regression. Learners can select a sample size, draw random samples from a dataset, and view sample observations as points with statistical annotations.
The strongest fit is a class studying sampling and statistical graphics. Rather than presenting statistical ideas only as text, the apps let learners inspect graphical displays and connect observations to annotations. The topic range includes confidence, resampling, and regression, with class activities covering statistical concepts and methods. This makes the collection relevant for guided exploration in a statistics course, particularly where working with samples and visual representations is central. It is a focused set of teaching tools, not a broad learning environment spanning many subject areas.
The materials are available free of charge and run in a web browser, so there is no paid plan distinction to weigh. StatPREP is an initiative of the Mathematical Association of America, the American Statistical Association, and the American Mathematical Association of Two-Year Colleges. The official site links to a newer set of apps while keeping the original collection available; instructors should distinguish which set they intend to use. Choose Little Apps for free, visual class work around its statistical topics. A course seeking a wider range of learning content or a single broader environment may prefer a different kind of resource.
