Beta DistributionConceptBeta Probability Distribution, Beta Density

The beta distribution is a probability distribution on values between zero and one, used in decision models to represent uncertainty in probabilities.

Beta LevelConceptBeta Error Rate, Type II Error Probability

The predetermined acceptable probability of failing to detect a true effect, with one minus beta defining a study's statistical power.
