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 …

Mean absolute deviation The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset. …

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 …

Explore how we can think of the mean as the balancing point of a data distribution. You know how to find the mean by adding up and dividing. In this article, we'll think about the mean as the …

Calculating the mean Calculating the median Choosing the "best" measure of center Mean, median, and mode review

To find the mean, you add up all of the numbers together and then divide the sum by the total amount of values (there are 4 values). Since only one of those numbers is increasing, the …

If the standard deviation is low, that means the numbers in your data set are clustered around the mean, whereas if the standard deviation is high, it means the numbers are more spread out …

This lesson teaches how to calculate the mean and mean absolute deviation (MAD) using a bar graph. The graph shows the number of bubbles blown by four people. The mean is found by …
