Rule | Min. Column | Max. Column | Beads | Percent |
---|---|---|---|---|
60%-75% within ±1 standard deviation of the mean | 14 | 17 | 155 | 77.5 |
90%-98% within ±2 standard deviations of the mean | 13 | 18 | 192 | 96 |
99%-100% within ±3 standard deviations of the mean | 11 | 19 | 200 | 100 |
As you can see, these results match pretty well the predictions of the empirical rule. In the first part our result is a little higher than expected, but the other two parts are just as predicted.
If you would like, you can repeat this experiment for yourself now. Simply click on the beadboard link in the toolbar, and follow the steps as laid out over the last few pages.
