Time to Evolve 2

This online task involves investigating pdfs and modelling though the uniform distribution. It combines some theoretical analysis of mean and variance and can be used to create an intuition that the sum of random variables tends to a normal distribution with the aid of a spreadsheet simulation (resource included). It is a common misconception that the sum of uniform random variables is also uniform and this problem will allow students to see that this is not the case in a meaningful context.
