Description
This video is another in the series looking at how we can investigate and compare data distributions which forms part of the Year 11 General Maths VCE course. This video looks at what we can use to find the spread of data. I look at three way including the range, the interquartile range and the standard deviation. Each has it's benefits and disadvantages! I explain how to find each of them (by hand and using a CAS) and what they are used for. There are lots of worked examples and the theory is explained in an easy to understand way.
