The normal distribution and the 68-95-99.7% rule | Year 12 General Maths | MaffsGuru.com ** 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. ** This maths video has been created for my students in Australia, but it is equally helpful for students in the USA, UK and other countries who are looking for good maths videos for both high school and middle school teachers.
