BR Sampling This module explores a variety of sampling schemes.
Students create a factory, ship lots, and determine if their sample is representative of the whole.
They see the cost of mistakes and dip into the world of statistical process control. Lesson 1 Census versus Survey Students define a census and a survey. They compare and contrast different types of data gathering. Actual cases studies are used to illustrate sampling error. Lesson 4 The Normal Approximation of a Binomial Distribution Students investigate the behavior of events where the only two choices are either the absence or presence of a desired characteristic.
