Linear Regression Example

Here is the video version of Lesson 17 from Stat Trek's free online tutorial covering the complete curriculum for Advanced Placement (AP) Statistics.

About This Video

This video lesson shows how simple linear regression can be used to predict the value of a single dependent variable, based on the value of a single independent variable. The video explains how to find the regression equation, how to use the regression equation, and how to compute the coefficient of determination. For each regression output, the video shows all computations step-by-step.

About Stat Trek's Video Series

A little history: About two decades ago, Stat Trek produced a free online tutorial covering the complete curriculum for AP Statistics. The tutorial, which can be found at https://stattrek.com/tutorials/ap-statistics-tutorial, was to designed to help students prepare for and pass the AP Statistics exam. Consisting of 69 easy-to-understand written lessons, the tutorial was very well-received.

Of course, there is always room for improvement. With that in mind, some students suggested supplementing the written lessons with video instruction. The Stat Trek video series is our response to that suggestion. So far, we've produced 45 video lessons, one video lesson for each of the first 45 written lessons from Stat Trek's' AP Statistics Tutorial.

The work continues. We're adding videos little by little. Eventually, we intend to have a video for each of the 69 written lessons from the tutorial.
