In this video, we look at continuous variation and standard deviation. First we look at the two different types of variation, which are continuous variation and discontinuous variation. We then explore how to calculate standard deviation and what standard deviation tells us about the amount of variation present.

Hi Shaun will you start A Level Physics in the next year or so? I do A Level Biology and Chemistry (and Maths) but also Physics and at the moment I don't have a savior for A Level Physics for Y13. Thank you.
