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.

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.

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 …

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

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

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

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

Learn about mean, median, and mode as measures of central tendency in statistics.
