Mean, Median, Mode
Central tendency measures
How It Works
Mean, median, and mode are measures of central tendency that describe the center of a data set. Range describes the spread of the data.
The mean, median, and mode are three commonly used measures of central tendency. The mean is the arithmetic average, found by adding all numbers and dividing by the count. The median is the middle value when all numbers are sorted in ascending order; if there is an even number of observations, the median is the average of the two middle numbers. The mode is the number that appears most frequently; a data set can have one mode, more than one mode, or no mode at all. The range is the difference between the highest and lowest values, providing a simple measure of spread.
