- Central Limit Theorem – you can roll up to 5 dice up to 10000 times and plot the frequency distribution of the total score. As you ‘roll the dice’ a second and third time, the cumulative score is shown so that the Normal distribution can emerge through repeated samples. Nice touch – imagine using this on an interactive whiteboard while asking questions from a well-primed group…
- Confidence Interval of the mean – you get multiple samples of 20 drawn from the same normal distribution. The applet then plots the data and the confidence interval. See how many CIs don’t overlap…. You get a choice of probability level (90%, 95% and 99%).
