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.
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!
