The following PowerPoint covers Chapter 6 from the Oxford textbook. Modelling Relationships: Linear Correlation and Bivariate Data. The Lesson contains various interactive activities such as Desmos Classroom for review exercises, Geogebra and Phet Simulations for showing line of best fit, least-squares, etc. There are also video links on how to used the GDC to find correlation and linear regression. The PowerPoint covers the following content below.
- correlation review (from chapter 3)
- finding correlation coefficient (PMCC)
- discussion about covariance
- interpreting PMCC
- correlation and causation
- coefficient of determination
- line of best fit
- interpolation and extrapolation
- reliability
- linear regression
- residuals
- piecewise functions
* step functions
All my PowerPoints have worked examples and exercises for students to complete. I have also added past paper questions in each section to get students accustom to the type and style of questions they will see on their exam. This PowerPower in particular comes with a Microsoft Teams quiz on Correlation and Linear Regression.
