Unformatted text preview: Introduction to statistics Definition: model Oversimplified, approximate, and useful representations of real world objects or phenomena. Predictions and inferences generated by the model should be capable of being verified or refuted by comparing them with real world observations. Examples A toy electric train is model of a real diesel train. It could be used to predict derailments if a curve were taken too fast, or if a curve has a particular bank angle. A college football video game match of Michigan versus Minnesota is a model of the real game that will occur this fall. The model includes various characteristics of each teams players and simulates each play in the game with random number generators. One could run several simulations with the video game to predict the real outcome. By comparing model predictions with real world observations one may determine that the model is inadequate and needs refinement. A refinement may lead to a more detailed alternative model....
