- 4. A study in which the participants are unaware of whether they are in the control group or the experimental group.
- 7. In an experiment, the group that does not receive the treatment.
- 8. The total group to be studied or described and from whom samples may be drawn.

- 12. The concept that people who volunteer to participate in research studies often differ from those who do not volunteer.
- 13. The study of behavior in a controlled situation.

- 15. Factors that are measured or controlled in an scientific study.
- 18. A relationship between variables in which one variable increases as the other variable also increases.
- 20. An experiment that uses both a control and an experimental group to determine whether the independent variable influences behavior and, if so, how it does so.
