Sample statistics divide by n−1 (use when your data is a sample of a larger population); population statistics divide by n (use when the data is the entire population).

What is this tool?

Computes the common descriptive statistics for a dataset: mean (average), median (middle value), mode (most frequent values), range, and both flavors of variance and standard deviation — sample (divides by n−1, for when your data is a sample of something larger) and population (divides by n, for when the data is everything). Numbers can be separated by commas, spaces, or new lines.

How to use it

  1. Paste or type your numbers, separated by commas, spaces, or line breaks.
  2. Read count, sum, mean, median, mode, and range.
  3. Use sample or population deviation/variance depending on what your data represents.
