5 Multiple choice questions
- includes a variety of different types of evidence supporting the characteristic being measured. Three common ways to measure construct-related validity include using a clearly defined variable, hypotheses based on theory to explain the variable, and logical and empirically tested hypotheses.
- random selection, random assignment
- or random sampling, is the process of drawing a research sample in which each member of a population has an equal chance ob being selected
- refer to the potential for a treatment protocol to have an effect based on the characteristics of the participant rather than those of the group as a whole

2. Know the characteristics of the participants in the study
3. Know the details of the study, such as where, when, and the extraneous events that may occur

5 True/False questions
random error → unpredictable fluctuations in instruments, participants, or conditions
descriptive studies → describe an existing phenomenon by using members to characterize individuals or groups
internal validity → a researcher's ability to determine whether a causal relationship exists between the independent variable and the dependent variable.
experimenter bias → can be used to make cause-effect determinations
Placebo effects → refers to the change in performance caused by the mere presence of others watching.
