FRACTIONAL FACTORIAL DESIGN

Conceptual Overview of Fractional Factorial Design The Fractional Factorial Design represents a sophisticated experimental framework utilized extensively in psychological research, engineering, and the social sciences to evaluate multiple factors simultaneously while minimizing the necessary number of experimental runs. Unlike a full factorial design, which requires testing every possible combination of all levels of all factors, […]

FRACTIONAL REPLICATION DESIGN

Introduction to Fractional Replication Design (FRD) The Fractional Replication Design (FRD) represents a powerful and often necessary methodology within experimental research, particularly when dealing with complex systems involving numerous independent variables, or factors. Fundamentally, FRD is defined as an experimental setup where researchers deliberately choose not to evaluate every possible combination of factor levels. Unlike […]
