This video continues the module relating to Data and Statistics for the VCE General Maths course (Units 1 and 2) relating to Determining the Value of Pearson's Correlation Coefficient. I look at what Pearson's Correlation Coefficient is and what it's used for before showing you how to find it. Whilst there is a really gross formula, it's good to know that your CAS can find it for you really easily. I show how to using a worked example and full CAS instructions all explained in an easy to understand way.
