Sample Space (Probability) The set of possible outcomes for an experiment sample size In statistics, _____ refers to the number of individuals measured or observed in a study. In probability, ______ refers to the number of possible outcomes in a trial or experiment. 3 techniques for finding sample space List, tree, table Theoretical probability Also called the "Actual," "Exact," or "Classical" Formula for theoretical probability Number of outcomes for event/ number of total possible outcomes for the event empirical probability probability that is calculated by conducting trials or experiments and recording the results. relative frequency aka empirical probability A way to approximate a percentage by dividing the number of times an event occurred in an experiment by the total number of trials. random experiment An experiment with an uncertain outcome in which all outcomes are independent of one another. Formula for relative frequency Number of times event occurred/ total number of trials Relationship between relative frequency and empirical frequency Law of large numbers Law of Large Numbers A law in probability that as the number of experiments gets larger, the relative frequency of an outcome will converge on the theoretical probability.
