Dr. Croteau explains to students in his methodology class that when they are using a mixed design, they are essentially using a factorial design with multiple independent variables.
Factorial design is a methodology that allows researchers to investigate the main and interaction effects of two or more independent variables on one or more outcome variables.This is a research methodology that goes beyond common single-variable experimentation.
It has been argued that factorial designs represent the true emergence of modern behavioural research, triggering a significant paradigm shift in how social scientists conceptualise their research questions and produce objective results.
