- experimental design
- internal validity
- a a researcher's ability to determine whether a causal relationship exists between the independent variable and the dependent variable.
- b includes members of a particular population who do not change over the course of the study
- c random selection, random assignment
- d can be used to make cause-effect determinations

- describes the characteristics of a population by selecting a representative sample of respondents to research
- used to survey different samples from a population whose members may change over time

Placebo effects → refers to the change in performance caused by the mere presence of others watching.
correlational designs → look at the degree and direction of the relationship between variables
