This video is another in the Year 11 VCE General Mathematics course looking at investigating and comparing data distributions. The work this year and next, will rely heavily on the work in this section of the course. Hence it's important to understand how to find the mean and median from raw data and why would would to do this. I spend the video looking at how to find the mean and median using both "by hand" and using the "CAS". I look at how to do this for stem and leaf plots and dot plots (as well as just list data). There are a number of worked examples and I explain everything in an easy to understand way.
