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 …

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.

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.

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!

The Mean Value Theorem states that if a function f is continuous on the closed interval [a,b] and differentiable on the open interval (a,b), then there exists a point c in the interval (a,b) such that f' (c) …

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.

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

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 …
