📊 Mean, Median, Mode Calculator - Central Tendency
Calculate central tendency for any data set
Mean, Median, and Mode Calculator
This tool computes the three core measures of central tendency for any list of numbers, along with the range and standard deviation. Just paste or type your values, separated by commas or spaces, and the calculator returns each statistic instantly so you can summarise a data set without manual arithmetic.
The mean is the arithmetic average: add all values and divide by how many there are. The median is the middle value once the numbers are sorted, which is useful when a few very large or very small figures would distort the average. The mode is the value that appears most often, and a set can have one mode, several, or none at all.
When each measure is most useful
Use the mean for evenly spread data such as test scores. Prefer the median for skewed data like incomes or house prices, where outliers pull the average away from a typical value. The mode helps with categories and repeated readings. Seeing the range and standard deviation alongside these tells you how widely the data is spread, giving students, teachers, and analysts a quick, reliable snapshot of any sample.
