Dice are cool and usually the epitome of randomness. This is a tiny little widget that (very simply) experiments with using z-Scores to predict whether a distribution of dice rolls are uniform and expected, or rigged and unexpected. Give it a go on the right! The mean and standard deviation of the sample are shown and calculated live for each roll of the die. The "Is this unusual?" button performs a simple z-Score calculation, z-Score being the number of standard deviations that a data point differs from the mean, but the sample's z-Score (which is what we calculate here) takes into account the entire sample, comparing our expected mean (about 3.5 assuming a fair 6-sided die), and the sample's mean. I'm too lazy to format the equations so just look them up. Enjoy!
