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.

The following PowerPoint covers the following topics following the Oxford textbook. Topics covered include: Functions * reation * domain and range * mapping diagrams * number system * set notation * interval notation * what is a function * vertical line test * function notation (numerical, graphical, and algebraic) * finding equation of functions from a mapping diagram Linear Models * recap equation of a line * rates of change * simultaneous equations * direct proportion * inverse functions * domain and range * horizontal line test (one-to-one) * finding inverse functions Arithmetic Sequences Arithmetic Series * sigma notation Simple interest Modelling Through the PowerPoint there are links to youtube videos, GeoGebra and Desmos interactives, and Desmos Classroom activities. The PowerPoint has worked examples, and student exercises. I have also put in past paper exam questions for each topic.

This unit contains 5 Powerpoints: Spearman’s rank hypothesis testing - chi-squared test of independence goodness of fit test goodness of fit - normal and binomial distributions t-test Through the PowerPoint there are links to Youtube videos, GeoGebra and Desmos interactive. The PowerPoint has worked examples, and student exercises. I have also put in past paper exam questions for each topic. I have also included an overall Statistics Test (2 parts short and long questions) and Chi-Squared test of Independence assignment, both with markschemes. As well as a review PowerPoint on the test of Independence. We sent a lot of time on this chapter as the idea was many students would use this for their IA’s, which they did.
