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.

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!

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

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

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.

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 …

Explore how we can think of the mean as the balancing point of a data distribution.

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

Step 1: Find the mean. Step 2: For each data point, find the square of its distance to the mean. Step 3: Sum the values from Step 2. Step 4: Divide by the number of data points. Step 5: Take the square root.

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.
