Please note that in my videos I use the abbreviations:
SSR = Sum of Squares due to the Regression
SSE = Sum of Squares due to Error.
Intro: 0:00
Y-hat line: 2:26
Sample error term, e: 3:47
SSR, SSE, SST: 8:40
R-squared intro: 9:43

Ever wondered WHY you have to SQUARE the error terms??
Here we deal with the very basics: what is regression? How do we establish a relationship between two variables? Why must we SQUARE the error terms? What exactly is SSE, SSR and SST? What is the difference between a POPULATION regression function and a SAMPLE regression line? Why are there so many different types of error terms??
Enjoy.
