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