Statistics Calculator

What is a statistics calculator?

A statistics calculator finds the mean, median, mode and range of a list of numbers. Example: for 4, 8, 15, 16, 23, 42 the mean is 18, the median is 15.5, there is no mode, and the range is 38.

How to use it

Enter numbers separated by commas, then tap Calculate.

Formulas

Mean = sum of all numbers ÷ count. Median = the middle number when sorted (for an even count, the average of the two middle numbers). Range = largest − smallest. Mode = the number that appears most often.

Example

For 4, 8, 15, 16, 23, 42: the sum is 4 + 8 + 15 + 16 + 23 + 42 = 108, so the mean is 108 ÷ 6 = 18. Sorted, the two middle numbers are 15 and 16, so the median is (15 + 16) ÷ 2 = 15.5. The range is 42 − 4 = 38.
