Sample Size Determination Techniques for Behavioral Sciences Research

Abstract

The purposes of this article are to inform readers about. - 1) how to gain better understanding regarding the sample size techniques for behavioral science research, 2) know how to determine the sample size for classical behavioral sciences research, and 3) know how to make a decision on the research sample size program for behavioral sciences research through an online program. The author has constructed a body of knowledge from synthesizing a wide range of resources such as academic documents, books, textbooks and articles on a sample size for behavioral science research. At the beginning of this article, the author provides information on approaches to sample size determination in behavioral research. Next, the article will present the research sample size determination using formulas, tables, and online programs from a variety of institutes. Finally, the research sample size determination using statistical analysis techniques for a large samples size such as factor analysis and structural equation modeling (SEM) is presented. It is the author’s intention that the readers are able to apply all knowledge most importantly to conduct research with high quality and reliability as well as to improve their body of knowledge on research methodology.
