Chapter 12
Normative Decision Making
John A. Swets Bolt Beranek and Newman Inc. Cambridge, Massachusetts
INTRODUCTION
This chapter was first drafted as part of a teaching manual for a new high- school course called "Reasoning Under Uncertainty," viewed as an alternative to present courses on probability and statistics. The course was developed for a computer-supported environment, in which the teacher and class--and groups of, say, two to four students--use a computer as a tool for gathering, manipulating, and displaying data.Emphasis in the course work is placed on visualization of processes (e.g., the approach of a distribution of sample means to a normal distribution as sample size or the number of samples increases); on linking multiple representations of a concept (e.g., representations of a distribution as a graph, equation, table of data, some summary statistics, and distribution- generating process); and on direct interaction of students with statistical objects (e.g., interactively moving a line on a scatter plot and seeing how a measure of the goodness of fit reflects the current position of the line). The course is described, along with field tests of some of it, by Roseberry and Rubin ( 1989, 1990).This chapter describes a unit of the concluding one of six course modules. The modules, two in each of three parts of the course, were entitled as follows:
Part I. Discovering Similarities and Differences:
Module 1: Describing groups.
