Between-Subjects Design — Independent Groups, Variance Control, and Statistical Analysis | Chapter 8 of Research Methods for the Behavioral Sciences
Between-Subjects Design — Independent Groups, Variance Control, and Statistical Analysis | Chapter 8 of Research Methods for the Behavioral Sciences Chapter 8 of Research Methods for the Behavioral Sciences focuses on the between-subjects design , one of the most widely used approaches in experimental research. In this design, each treatment condition is tested on a different group of participants, allowing clean comparisons across independent groups. This chapter outlines the advantages of between-subjects experiments, identifies major threats to internal validity, and explores strategies to reduce variance and improve reliability in results.

In a between-subjects design, each participant is exposed to only one condition of the independent variable. This approach avoids carryover effects and ensures the independence of observations, mak...
