Another common example of a within-subjects design is medical testing, where researchers try to establish whether a drug is effective or whether a placebo effect is in order. The researchers, in the crudest form of the test, will give all of the participants the placebo, for a time, and monitor the results.
What is a 2x2 within subjects design? In a 2x2 design, researchers examine how two independent variables with two different levels impact a single dependent variable. For example, imagine a study where researchers wanted to see how the type and duration of therapy influence treatment outcomes.
Two statistical procedures that are used to analyze within-subjects designs are the paired samples test (also called the dependent t-test) and analysis of variance (ANOVA). A paired-samples test is used if you have only one independent variable and that variable only has two levels.
In a within-subjects design, each participant experiences all conditions, and researchers test the same participants repeatedly for differences between conditions.
Example: Within-subjects design for different treatments You're studying the effects of different messaging styles (your independent variable) on generosity (your dependent variable). Every participant is presented with 5 different short stories about climate change. Each story uses a different tone and style.
