How to use it

  1. Type or paste your numbers. Commas, spaces, tabs and line breaks all work, so you can paste a spreadsheet column.
  2. Read the mean, median and mode, plus the spread of the data.
  3. Copy the summary to paste into a report or assignment.

Examples

Test scores

For 72, 85, 85, 90 and 98 the mean is 86, the median is 85, the mode is 85 and the range is 26.

When mean and median differ

Incomes of 30, 35, 40, 45 and 250 (thousand) have a mean of 80 but a median of 40. The median is usually the better “typical” value when one figure is extreme.

Three kinds of average

The mean adds every value and divides by the count. The median is the middle value once the list is sorted (or the mean of the two middle values for an even count). The mode is the value that appears most often; a list can have several modes or none.

Standard deviation measures spread. Use the sample version when your numbers are a sample of a larger group, and the population version when you have every value.

mean = Σx ÷ n · sample SD = √(Σ(x − mean)² ÷ (n − 1))

Frequently asked questions

Which average should I use?

Use the mean for symmetric data without outliers, the median when a few extreme values would distort the mean (incomes, house prices), and the mode for the most common category or value.

What if no number repeats?

Then there is no mode, and the calculator says so rather than picking an arbitrary value.

Can I paste numbers with thousands separators?

Yes, as long as they use commas with exactly three digits after them, like 1,250. To avoid ambiguity, separate values with spaces or new lines when they contain commas.
