Chi Die Description
Suspect you have a die which is a bit too (un)lucky? This app allows you to easily record die rolls for your collection of dice, and provide statistics on just how fair your dice really are.
Mean : Average of the recorded rolls
Chi Squared : This statistic provides overall determination on whether or not each side of a die is equally probably. Higher values indicate increasing confidence that the die is unfair. The percentage value is the 95% confidence level. The number of rolls needed should be at least 5 times the number of sides of the die, but ideally much higher.
Each individual side is also analyzed against a binomial distribution, to find sides that come up more or less often than they statistically should.
The most recent recorded roll is highlighted in blue, and in case of an accidental mis-press, can be undone by a long press on the highlighted value.
