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

Learn about mean, median, and mode with Khan Academy's comprehensive review of these fundamental concepts in statistics.

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.

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 …

The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set. It can be used to quantify the spread in the data set and also be helpful in …

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

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

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! Created by Sal Khan and Monterey Institute for Technology and …

To find the Mean Absolute Deviation (MAD), first calculate the mean (average) of your data set. Next, find the absolute difference (distance) between each data point and the mean. Sum up these …

So, really standard deviation is: calculating the difference of each item to the mean, and squaring that value. Once you calculate all the values in a different list, you take the mean of that. Then, you take …
