Formula for standard deviation and correlation coefficient

[Agimo]

Does VCAA require further students to know how to use the formulas to find standard deviation and correlation coefficient or do we only need to know how to find them through the CAS calculator.

Hey Agimo!
Further is pretty nice and will allow you to use your calculator all the time in all assessments. You won't ever be asked to find the SD or correlation coefficient by hand, so as long as you can get it via the calculator, you'll be set.

I was just a bit confused because the cambridge further maths text book teaches you how to calculate the formulas by hand.

If in doubt, refer to the study design. Textbooks will often include content that goes slightly beyond the scope of the course to 'fill out' their textbooks. As AngelWings said, definitely don't need to know

I wouldn't bother using the formula as you have to plug in many numbers and doing so you can make mistakes unless you know what you're doing, and as stated above, you can just do it on the calculator in the spreadsheet page
