## Standard Error of the Estimate

Length: 13 minutesAuthor: JasonComplexity: Easy Regression is all about making predictions. When you make a prediction, you can expect to make mistakes (errors). The Standard Error of the Estimate measures how big of an error we can typically expect. I go through the calculation and the interpretation and introduce the Sum of Squares Error (SSE) along the way.

## Interpreting the Coefficients

Length: 12 minutesAuthor: JasonComplexity: Easy What good is an equation if you don't know what it means? Here I explain what the intercept and slope of the equation line mean. I do this in the context of the example that we've been following throughout these videos, but I also give you a general version of the interpretations that will work for any simple linear regression questions.

## Introduction to Simple Linear Regression (Preview)

Length: 5 minutesAuthor: JasonComplexity: Easy In this video I introduce the single exam question that will be used to teach this entire chapter. There is very little variation possible with simple linear regression questions, so this question will do a great job of preparing you for any short answer questions from Chapter 16 that may appear on your exam.

## The Least Squares Regression Line

Length: 10 minutesAuthor: JasonComplexity: Easy The least squares regression line ( also known as the least squares regression equation, or simply the regression equation) is usually the first question worth marks on a simple linear regression question. We did most of our calculations when we found the sums in an earlier video, so determining the values (coefficients) of this equation will be quick and easy!
