About the Statistics Calculator

This calculator turns a numeric data set into a concise statistical summary without requiring a spreadsheet.

How to use it

  1. Enter the observations as a comma-, space-, or line-separated list.
  2. Calculate to sort and summarize the data.
  3. Compare the center, spread, and quartiles before drawing conclusions.

How the measures work

The mean is the sum divided by the count, while the median is the middle sorted value. Range measures maximum minus minimum; variance and standard deviation describe spread around the mean.

Population calculation

Variance here divides by the number of entered values, so it describes the entered set as a population. Statistical software may instead use n minus 1 for a sample estimate.

Example

For 4, 7, 7, 9, 10, and 12, the median is 8, the mode is 7, and the range is 8.
