The Law of Averages

Investigate the Law of Averages


In illustration of the law of averages, you will observe that as the number of trials increases, the percentage of successes approaches the expected percentage of successes while the difference betweent the observed and expected number of successes increases.


Scale - Note that the scale on the horizontal axis is not constant. The plots may appear to show sudden jumps or dramatic differences at 100 and 1000 tosses, this is a result of the change of scale at those positions.

Display The 'Display' menu in the upper left hand corner of the applet allows the user to adjust the speed of the experiments and change the appearance of the plot.
