How to use the statistics calculator
- Type or paste your numbers, separated by commas, spaces or new lines.
- Read the results as you type.
- Copy the results to use them elsewhere.
Sample or population?
Use the sample standard deviation (dividing by n − 1) when your numbers are a sample from a bigger group, which is usually the case. Use the population figure (dividing by n) when you have every value of the whole group.
Quartiles
Quartiles are worked out the same way as Excel's QUARTILE.INC and Google Sheets' QUARTILE, so the results match your spreadsheet.
