Although there may be some main effects mixed in with the interaction, whats important here is that there is a unique combination of levels of factors that stands out as superior: psychotherapy done in the inpatient setting. The two levels for each of the drugs (or factors) is ''Yes, the patient received the drug.'' You have to be very careful in interpreting these results because higher scores mean the patient is doing worse. Some key advantages of factorial design are: A factorial design is defined as an experiment that has multiple factors or independent variables. Participants are given one of three different drug doses, and then asked to either complete a simple or complex memory task. For instance, testing aspirin versus placebo and clonidine versus placebo in a randomized trial (the POISE-2 trial is doing this). 15 0 obj <> endobj b.

For these examples, lets construct an example where we wish to study of the effect of different treatment combinations for cocaine abuse. She has just added a second independent variable of interest (sex of the driver) into her study, which now makes it a factorial design. false; it doesn't meet the 4 criteria for causality, true/false: a measured/subject variable can have causal interpretability, true; having this many IVs gets too complicated, true/false: it is rare to do a 4-way design, a 2x2 design has 4 combined conditions (cells).

Expand the larger factorial such that it includes the smaller ones in the sequence. However, lets imagine that Sarah is also interested in learning if sleep deprivation impacts the driving abilities of men and women differently. I'm planning an experiment with three independent variables (IV) and one dependent variable (DV) and would like to get an idea of what methods of data analysis might be appropriate and what corresponding sample size I should aim for.
