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 …

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

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 …

Calculate the mean, median, or mode of 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!

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.

Learn Statistics intro: Mean, median, & mode Mean, median, & mode example Calculating the mean

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.

Take a sample from a population, calculate the mean of that sample, put everything back, and do it over and over. How much do those sample means tend to vary from the "average" sample …
