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.

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.

. Mean: The mean is just another word for the average. To find the mean of a set of numbers, you add up all the numbers and then divide by how many numbers there are. Here's how you do it: …

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

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.

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

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 …

Sal continues on from the previous video to derive the mean and variance formulas for the Bernoulli distribution.
