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

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: …

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 …

Take a sample from a population, calculate the mean of that sample, put everything back, and do it over and over. No matter what the population looks like, those sample means will be roughly …

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.

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.

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!
