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 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!

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

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.

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