Description
So you've woken up in the night wondering what the 68-95-99.7% rule is and why we would call a distribution normal? Well, this is going to the video for you. I take a small amount of time to talk through what a normal distribution is and why we need it. I look at standard deviations and how we can split the normal distribution into chunks. I relate this to the VCE and then look at the percentages which lie between the standard deviations AND the individual sections. I end the video with an example which explains how to read, construct and use a normal distribution curve.
