- 3. A sample drawn in such a way that known subgroups within a population are represented in proportion to their numbers in the general population.
- 5. To build or form by putting together parts.
- 6. A prediction or assumption about behavior that is tested through scientific research.
- 7. A relationship between variables in which one variable increases as the other variable also increases.
- 13. 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.
- 14. The concept that people who volunteer to participate in research studies often differ from those who do not volunteer.
- 15. In an experiment, the group that does not receive the treatment.
- 16. The study of behavior in a controlled situation.
- 17. A measure of the distance of every score to the mean.
- 18. A controlled scientific procedure to determine whether certain variables manipulated by the researcher have an effect on other variables.
- 20. Factors that are measured or controlled in an scientific study.
- 21. A type of research in which the same people are studied over a long time period.
- 23. A representative segment of a target population.
- 24. An unpleasant stimulus between two variables in which one variable increases as the other variable decreases.
- 25. An agreement by an individual to participate in research after receiving information about the purpose of the study and the nature of the treatment.
- 26. An experiment in which neither the participant nor the researcher knows whether the participant has received the treatment or the placebo.
