Coefficient of Variation Calculator

Paste your numbers. Calculate coefficient of variation as a percentage, mean and standard deviation. 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. Paste your numbers
  2. Check your values and calculation settings.
  3. Calculate, review the method, and save your results.

How it works

Calculate coefficient of variation as a percentage, mean and standard deviation from your own values. Use the fictional sample to try the calculation. CV is standard deviation divided by the mean, multiplied by 100. Interpret it for positive ratio-scale measurements with a meaningful zero.
