What is Mean, Median & Mode in Statistics? - [6-8-13]

View more at www.MathAndScience.com. In this lesson, you will learn how to calculate and compare the mean, median, and mode of a data set in statistics. We learn that the mean is used when there are no outliers in the data, and we often use the median when we know there are outliers in the data. We use the mode when the data is non-numerical in nature. We will construct a line plot of the data to help us visualize how the mean, median, and mode compare with one another.
