How to do Simple Linear Regression by Hand (14-4)

Simple Linear Regression is used to predict the value of an output variable from a predictor variable. Although it is unlikely that you will be calculating many regression equations by hand, doing an example by hand is a great way to really understand regression. We will begin with the assumptions and the necessary settings for null hypothesis testing, then I will show you an example using the regression formulas with a simple dataset. This will get you acquainted with the regression procedure.

This video teaches the following concepts and techniques:
Regression formulas for calculation

Link to a Google Drive folder with all of the files that I use in the videos including the regression datasets. As I add new files, they will appear here, as well.

Thank you so much for all your videos. I have had an allergic reaction to the word regression and any kind of statistical tests, and a crippling fear of any statistics for years. Your lessons are wonderful.

May I ask, how is the formula derived? I keep on searching and searching but one thing, for me, is that I can never fully do something without understanding it first. Please tell me.
