Some Probabilities Available from Desk Calculators and Their Relation to Tables

Modern desk calculators compute distribution functions for many of the standard tabled distributions.Two such machines and some of their capabilities are discussed.Generally more is available from the calculators than is found in voluminous tables.One of the biggest advantages of the machines over tables arises from their capacity to compute probabilities for the two parameter F distribution, a set of values that is cumbersome to tabulate.
