GLM1071   circle graphYcircle graph:ÖA graph that compares parts of a set of data as a percent of the whole set. complementary events™complementary events:ÖThe events of one outcome happening and that same outcome not happening. The sum of the probabilities of complementary events is 1. experimental probability‹experimental probability:ÖThe ratio of the number of positive outcomes to the total number of events or trials in a probability experiment. outcomekoutcome:ÖOne possible result of a probability event.ÖExample: 4 is an outcome when a number cube is rolled. percent\percent:ÖA ratio that compares a number to 100.ÖExample:Ö76 out of 100 isÖ76 percent or 76%.  populationVpopulation:ÖA large group of data from which a sample of statistical data is selected.  probabilityÅprobability:ÖThe ratio of the number of favorable outcomes for an event to the number of possible outcomes of the event.ÖP(a) = (number of favorable outcomes) / (total number of possible outcomes). randomLrandom:ÖOutcomes occur at random if each outcome is equally likely to occur.  sampleHsample:ÖSome portion of a larger group selected to represent that group.   sample space=sample space:ÖThe list of all possible outcomes for an event.  surveycsurvey :ÖA question or set of questions designed to collect data about a specific group of people.Ö  theoretical probabilityptheoretical probability:ÖThe ratio of the number of favorable outcomes to the total number of possible outcomes.   tree diagramWtree diagram:ÖA diagram used to show the total number of possible outcomes of an event.ŽY
