Document Summary

Did a change in a cause a change in b? (causality) Experimental: manipulation of one or more variables and there needs to be random assignment in which every participant has an equal and likely chance to being placed into any condition in order to establish causality. Epidemiology: randomized controlled trials in which one group receives a placebo and another receives the medication. Placebo: inert form of the medication or the implementation. Nocibo: actually afraid that the pill will have negative side effects. To make sure that the effect is coming from the placebo itself! Within-person design: withdrawal design: you get withdrawal of treatment during phase (s) of a study to show the effects that it has on the target behavior. In this design, the researcher collects baseline data and then implements a treatment. Ex-post-facto: following after the fact that something has occurred and examines whether a pre-existing condition could have caused a difference in groups of subjects.
