Quick guide
- Paste data and generate charts (with exports and steps).
- Build frequency tables and histograms for grouped or raw data.
- Fit a line, check residuals, and share the result by URL.
Tools
- Quick charts from pasted data — scatter / box plot + regression (with steps, PNG/PDF)
Paste spreadsheet data to generate scatter and box plots instantly. Includes OLS, Theil–Sen, and polynomial regression with step-by-step math plus PNG/PDF export.
- Distribution sampler – random samples & histograms (normal, Poisson) | CalcBE
Generate random samples from common distributions (normal, log-normal, gamma, poisson, and more). Visualize histograms, check summary stats, and download CSV/JSON — runs locally in your browser.
Calculators
- Histogram & cumulative frequency from grouped data | CalcBE
Enter grouped or raw data to build a derived frequency table, histogram (frequency or frequency density), and cumulative frequency ogive. Detect unequal widths, highlight modal/median classes, copy a shareable URL, an…
