PSYB01H3 Chapter Notes -Statistical Hypothesis Testing, Factor Analysis, Analysis Of Variance
Document Summary
Study design that is ideally suited to disentangle both direct and interactive influences on measured responses: Complex experimental design: used when a researcher seeks to manipulate 2 or more iv at the same time --> referred to as factorial designs. -> more realistic, b/c if allows researcher to examine how ivs interact with each other. -> more efficient since it isnt limited to one at a time variable manipulation. Multifactorial is term used for exp that vary two or more iv and will provide direct test of the main effects of each iv as well as interaction b/w and among ivs. Can vary ivs between subjects, others can vary them within subjects and some can combine. Compared to single factor experiment where there is only one iv and you can just keep adding conditions/levels. A new iv is devised and incorporated into research design.
