institutional review board (IRB)
committee of administrators, scientists, and community members that reviews proposals for research involving human participants
informed consent
process of informing a research participant about what to expect during an experiment, any risks involved, and the implications of the research, and then obtaining the person’s consent to participate
deception

debriefing

institutional animal care and use committee (IACUC)

correlation
relationship between two or more variables; when two variables are correlated, one variable changes as the other does
positive correlation
two variables change in the same direction, both becoming either larger or smaller
negative correlation
two variables change in different directions, with one becoming larger as the other becomes smaller; a negative correlation is not the same thing as no correlation
cause-and-effect relationship
changes in one variable cause the changes in the other variable; can be determined only through an experimental research design
cofounding variable
unanticipated outside factor that affects both variables of interest, often giving the false impression that changes in one variable causes changes in the other variable, when, in actuality, the outside factor causes changes in both variables
