# 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

outcome.)

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.)
