SALT (Statistical Analysis and Learning Tool) review
A free web tool for exploring datasets and practicing introductory statistics.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SALT (Statistical Analysis and Learning Tool) is a web-based statistics tool for students in introductory courses. It can be accessed as a standalone website or through selected SALT-enabled WebAssign questions, where students can import the question's dataset. It is suited to learners who want to examine data and carry out statistical procedures alongside coursework, rather than follow a sequence of lessons. Instructors can configure assignments to provide full SALT functionality, distribution calculators only, or no SALT access.
The tool covers a broad set of introductory analysis tasks: students can preview and edit datasets and variables, use existing data or upload CSV files, create descriptive statistics and charts, explore distributions and sampling, and run inferential procedures. These include bootstrap confidence intervals and randomization hypothesis tests, as well as regression analysis. That range makes SALT useful for practicing methods across a course, while its focus remains on analysis rather than guided instruction: it does not provide guided lessons, simulations, or probability experiments.
Standalone SALT is free to access, according to the product information, and runs on the web. Its WebAssign connection is relevant for students whose coursework includes SALT-enabled questions, but access through those questions is selective and instructors control which SALT features an assignment offers. Choose SALT if the goal is to work directly with datasets and statistical procedures, especially alongside WebAssign. Students seeking structured lessons or simulated experiments should look for a learning tool centered on those activities instead.
