About this lesson
This video looks at how we can use a linear regression equation (or least squares regression equation) to predict values. It forms part of the Year 11 General Mathematics course for VCE Mathematics. I look at how we can use the CAS to find a linear regression line and show examples of how we can predict values from this. There is also a discussion about Interpolation and Extrapolation and how models might break down. The explanations are given so they are easy to understand.
