Statistics- Module 10

Statistics- Module 10 Probability - Refers to the relative frequency of a particular outcome occurring over an infinite number of trials or occasions Proportion - Varies between .00 and 1.00 It will not occur - If the probability of an outcome is .00, it is certain that it will... It will occur - If the probability of an outcome is 1.00, it is certain that it will... Equally likely model - The generating event yields possible outcomes that are each equally likely. Mutually Exclusive Outcomes - The outcome of a particular trial precludes any other outcome on that same level. Always refers to a single trial. Addition Theorem - The probability of any of the possible outcomes occurring on a particular trial is the sum of their individual probabilities Independent Outcome - The outcome of one trial has no relation to the outcome of another trial. Always refers to a series of trials. Multiplication Theorem - The probability of a series of particular outcomes occurring on successive trials is the product of their individual probabilities. Applies only to a series of trials.
