7th Grade Module 5

New or Recently Introduced Terms

 Probability (A number between and that represents the likelihood that an outcome will occur.)

 Probability model (A probability model for a chance experiment specifies the set of possible
outcomes of the experiment—the sample space—and the probability associated with each

 Uniform probability model (A probability model in which all outcomes in the sample space of a chance experiment are equally likely.)

 Compound event (An event consisting of more than one outcome from the sample space of a
chance experiment.)

 Tree diagram (A diagram consisting of a sequence of nodes and branches. Tree diagrams are
sometimes used as a way of representing the outcomes of a chance experiment that consists of a
sequence of steps, such as rolling two number cubes, viewed as first rolling one number cube and then rolling the second.)

 Simulation (The process of generating “artificial” data that are consistent with a given probability model or with sampling from a known population.)  Long-run relative frequency (The proportion of the time some outcome occurs in a very long sequence of observations.)

 Random sample (A sample selected in a way that gives every different possible sample of the same size an equal chance of being selected.)  Inference (Using data from a sample to draw conclusions about a population.)
