Central Limit Theorem
Graphic demonstration of the Central Limit Theorem. Use sliders to change shapes of graphs. Two tabs  one to demonstrate nonnormal distributions, one to demonstrate standard deviation of estimations of normal distributions.




Poisson Diagram
Visual diagram highlighting key maths contributory ideas to the Poisson Distribution.




Statistics Distributions
Summary document highlighting key features, criteria, examples, notation and equations of the binomial, normal, poisson and geometric distributions. PDF here.




Graphs of Distributions
Dynamic graphs of the binomial, normal and poisson distributions. Use sliders to change values and shapes.








ChiSquared Concept Questions
A set of questions designed to assess students understanding of the chisquared hypothesis test. These questions all involve 'single' sets of data, in preparation for contingency tables later on.




Trying to be Random
Imagine rolling the die 40 times, what may the results be? Then carry out a chisquared test to assess your randomness.




Combinations
How many ways to choose 0, 1, 2 or 3 from 3 cards. Or 04 from 4 cards, or even 5! (An introduction to Pascals).
