Statistics Step Explainer Analyzer is a free, browser-based tool that helps you understand a dataset at a glance. Descriptive statistics, correlation, and least-squares regression where every metric expands into its full worked calculation — with histogram, box plot, and scatter charts. It's built for speed and privacy: Everything runs locally in your browser — your data is never uploaded to a server. No sign-up, no installs, and no daily limits.
Profile the data first so missing values, types, duplicates, and outliers are visible before you edit it.
Review the preview, copy or download the result, and keep everything local in your browser.
