Least-squares regression line

Regression: fitting lines to data

Year 12

This video is the first is a series of new videos which will explain how to do least squares regression to find the line of best fit for a scatter plot of roughly linear data. It looks at what the line of best fit is, how to find it using residuals and the least-squares method and what we use this for. Examples are used and backed by Cambridge Further Maths Units 3 and 4 textbook. This is a great video which is well explained and meets the needs of the current study design.
