Mean, Median and Mode Calculator
Calculate mean, median, mode, sum, range, and extremes for a list of numbers.
What each measure means
The mean is the sum divided by count. The median is the center of the sorted list. Modes are values tied for highest frequency; if each occurs once, there is no mode.
Mean = sum of values ÷ count
Entering number lists
Separate numbers with commas, semicolons, spaces, or line breaks. Decimal points remain unambiguous in English input.
