Demonstrates the value of spreadsheets for teaching sociology using Lotus 1 2 3 as an example. Shows how a Cholesky factorization, an eigenstructure solution, a correlation analysis, and a discriminant analysis may be performed using a spreadsheet or a BASIC program (included). (BSR)

Describes an exercise used as a follow-up activity to a lecture presentation exploring the basic methodology and theory of shoot tip cultures. Utilizes a factorial experimental design which allows for the determination of the effects of each factor alone and in combination with each other. Other concepts emphasized include dependent and…

Uses inexpensive equipment to demonstrate, through factorial design, an interaction between genetics and environment. Provides instructions for introducing and conducting the experiment, reporting that significant results are usually obtained. Notes the exercise is appropriate for experimental psychology, developmental psychology, behavior…

Described is an experiment in which factor analysis is used to identify and quantify the components of mixtures containing up to four species. Discussed are the theory, procedures, and sample results for this activity. (CW)

Provides background theory and an experiment relating to chemometrics. Describes the phenomenon where solutions are dichromatic or dichromic. Discusses the difficulty students have in describing such solutions that appear to be several different colors at the same time. (TW)

Discussed are ways in which students can generalize both quadratic or cubic situations. Generalizations are produced using the factor method, repeated linear generalizations, means of the mean, and through the use of differences. (KR)
