This video continues the work relating to VCE General Maths Units 1 and 2 to look at Using the least squares regression line to model a linear association. Pretty long title but not too long a video! I look at how the CAS can take a table of values and turn it into a Least Squares Regression Line. I look at how the CAS can do this for you using the graphs and tables but also how we can uses to simple formulae to help us find the intercept and gradient of the least squares regression line. I continue to use the same examples I have been using in previous videos to explain the concepts in an easy to understand way.
