Correlation Coefficient Calculator

Enter two lists with matching rows. Calculate pearson correlation and paired deviations. Review the method and copy or download your results.

Enter a grid, paste values, or choose CSV, TSV, JSON, JSON Lines, XLSX, text or a statistics project. XLSX requires a worksheet choice and imports values only. Review headers and column mapping before calculating. The workspace supports up to 2 MB, 20,000 rows and 100,000 cells.

Import settings

Column mapping is available after opening the data. JSON object keys become column names. Grid column names are separate from its data rows.

  1. Enter two lists with matching rows
  2. Check your values and calculation settings.
  3. Calculate, review the method, and save your results.

How it works

Calculate pearson correlation and paired deviations from your own values. Use the fictional sample to try the calculation. Pearson r measures linear association between paired numeric values. Both lists need nonzero spread. Correlation alone does not establish causation.
