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

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, 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 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 …

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.

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!

Which mean are we talking about in "standard error of the mean"? The question comes up, as there are at least 3 types of means in the question: the actual population parameter, means of …

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.
