Enter, paste or import data to calculate descriptive statistics, create charts, compare groups, examine relationships and run common statistical tests—directly in your browser.
Use the helper to choose from the tests available in this workspace.
Use the workspace for descriptive statistics, frequencies, charts, correlation, regression and common introductory hypothesis tests. Data processing happens in your browser; the dataset is not uploaded to Calc for Class.
Numeric variables contain measured or counted values. Ordinal variables have a meaningful order, while categorical variables represent groups without requiring numeric spacing.
The workspace reports both sample and population standard deviation. Sample formulas use n − 1; population formulas use n.
Blank cells and configured missing codes are never treated as zero. Every analysis reports how many rows were used, which variables were required and whether available-case, pairwise or listwise deletion was applied.
Use descriptive statistics, histograms and box plots to understand the centre, spread and shape of a distribution.
Use grouped summaries, t-tests or one-way ANOVA when the outcome is numeric and observations belong to groups.
Use correlation for association and regression when you want an equation that predicts one numeric variable from others.
Yes. It is free to use and does not require an account.
No dataset is uploaded to Calc for Class in this version. Calculations and saved projects run locally in your browser.
Yes. Paste tab-separated rows and columns directly into the grid or use the Paste data dialog.
One-sample, independent and paired t-tests, one-way ANOVA and the chi-square test of independence are included.
Percentiles use linear interpolation based on ordered values, equivalent to the common type-7 quantile convention.
You can export the data as CSV, save projects locally, print results and download charts as SVG.
