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!
Practice calculating the mean (average) of a data set. The mean gives us a sense of the middle, or center, of the data.
Learn how to calculate the mean by walking through some basic examples & trying practice problems.
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.
Practice calculating and interpreting the mean and standard deviation of a discrete random variable.
