In elementary probability, some students may be asked to toss a fair coin 200 times, while others 'make up' the results. Usually, the data from actual tosses can be distinguished from the fake by counting the length of the longest run - students generally underestimate. The run data from coin tossing and some other related experiments will be explored using the TI-83+.
