Experimenter-Controlled Decisions in the Design and Analysis of Psychological Research.

Abstract

This paper reviews certain statistical rationales and procedures that can be useful to research staff in designing and analyzing research. It consists of three parts. The first deals with the necessity of computing the number of subjects required by a given experiment and presents rationales and procedures. The second part explains the advantages of having equal numbers of subjects in experimental treatment 'conditions' or 'cells,' and shows to what extent bias may affect analysis of unequal cell frequencies. The third part outlines the sometimes drastic effect of making multiple comparisons on the same data and suggests alternate procedures. (Author)
