Regression 1: Slope and intercept

In this video, I introduce the basics of simple linear regression (SLR). Topics include (1) an intuitive understanding of how to fit a regression line, (2) some equations for the slope and intercept in SLR, and (3) how to interpret the slope and intercept in SLR.

should it be SSE=(800-a-b*640)^2?

[intromediateecon]

@breastplates Yes, sorry about that. I meant to put parentheses around the (a+b*640).

This was super helpful. My professor sucked at explaining this! He didn't even work out a problem, just read examples from slides.....
