This video looks at how we can split a normal distribution (or data which is normally distributed) into approximately 6 sections where the width of each section is a standard deviation. We can then investigate percentage of data lying within multiple standard deviations. This is a really important part of the Year 11 General Mathematics course as it is used in Year 12 extensively. I explain all you need and use some examples from the Cambridge VCE Textbooks to help you understand this topic.
