Uses the random-number generator and list features on the TI-83 graphing calculator to generate lists of sample means to help illustrate the concepts discussed in introductory statistics courses. (ASK)

Discusses the use of the Excel computer program to develop and distribute simple models that provide a clear visual representation of a chosen probability distribution's properties to students. (ASK)

Describes classroom activities and shows that statistics is a practical tool for solving real problems. Presents a histogram, a stem plot, and a box plot to compare data involving class enrollments. (YP)

Summarizes a simple design algorithm which identifies nested loops of equations which must be solved by trial-and-error methods. The algorithm is designed to minimize such loops, provides guidance to the selection of variables, and delineates the order in which systems of equations are to be solved. Examples are included. (TW)

Outlines differences between classical statistics and exploratory data analysis. Provides examples in the use of the exploratory techniques. (YP)
