Finding r by hand

Using the CAS to find the value of 'r'
VCAA Question
Thanks for watching
This video forms on video as part of the core module on data analysis. I take a look at how to use pencil and paper methods alongside the CAS to find the correlation coefficient given a set of data. There is a formula I use to find the value of 'r'. This type of question comes up in exams all the time and I do all I can to make the content as easy to understand as I can.
