Mean, median, and mode are different measures of center in a numerical data set. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset.

Learn how to calculate the mean by walking through some basic examples & trying practice problems.

Calculate the mean, median, or mode of a data set!

This Khan Academy article reviews mean, median, and mode concepts with examples to help understand their application in statistics and probability.

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 …

Practice calculating the mean (average) of a data set. The mean gives us a sense of the middle, or center, of the data.

Mean absolute deviation The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. …

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.

Explore how we can think of the mean as the balancing point of a data distribution.
