Warning: This has nothing to do with Marmite, Vegemite or Jam! This video continues looking at continuous random variables. In previous videos, we have looked at what a continuous random variable is and how to find the median and mean. This video looks at how to find the variance and standard deviation for continuous random variables. There are a few worked examples and lots of puns, witticisms and great explanations.
