Learn about mean, median, and mode with Khan Academy's comprehensive review of these fundamental concepts in statistics.
The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
This Khan Academy article reviews mean, median, and mode concepts with examples to help understand their application in statistics and probability.
Here we give you a set of numbers and then ask you to find the mean, median, and mode. It's your first opportunity to practice with us!

Practice finding the median of a data set. Like the mean, the median gives us a sense of the middle, or center, of the data.
Calculating the median in data sets of odd (above) and even (below) observations The median of a set of numbers is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as the “middle" value. The basic feature of the median in describing data compared to the mean (often simply described as ...
The median is the middle number in a sorted ascending or descending list. It can be more descriptive of the dataset than the average. It’s quite different from the mean.
