Maths Tutorial: Calculator Steps for summary statistics

VCE Further Maths Tutorials, Core (Data Analysis) Tutorial 7 - Summarising Data. This vid is an add-on for tute 7 to show you the calculator steps for working out the summary statistics. Uses a TI-83 calculator to demonstrate. I know that's very 'last century', but I can't get a simulation of a CAS on the screen so don't know how to shoot demonstrating with that, sorry.
