vocab terms for PSY 200 chapter 2
Show Answers:

  1. a descriptive research technique in which the effort is focused on a single case, usually an individual
    case study
  2. the principle that personal information obtained from a participant in research or therapy should not be revealed without the individual's permission.
  3. an uncontrolled variable that change along with the independent variable
    confounding variable
  4. a statistic that indicates whether two variables vary together in a systematic way; correlation coefficients vary from +1.00 to -1.00.
  5. at the conclusion of an experimental session, informing the participants about the general purpose of the experiment, including any deception that was involved.
  6. the behavior that is measured or observed in an experiment
    dependent variable
  7. methods designed to observe and describe behavior
    descriptive research
  8. mathematical techniques that help researchers describe their data
    descriptive statistics
  9. neither participants nor research observers are aware of who has been assigned to the experimental and control groups; its used to control for both subject and experimental expectancies
    double-blind study
  10. a technique in which the investigator actively manipulates the environment to observe its effect on behavior
    experimental research
  11. the extent to which results generalize to other situations or are representative of real life
    external validity
  12. the aspect of the environment that is manipulated in an experiment.  It must consist of at least two conditions.
    independent variable
  13. mathematical techniques that help researchers decide whether data are representative of a population or whether differences among observations can be attributed to chance.
    inferential statistics
  14. the principle that before consenting to participate in research, people should be fulling informed about any significant factors that could affect their willingness to participate
    informed consent
  15. the extent to which an experiment has effectively controlled for confounding variables; internally valid experiments allow for the determination of causality.
    internal validity
  16. the arithmetic average of a set of scores
  17. the middle point in an ordered set of scores; half of the scores fall at or below the median score, and half fall at or above the median score
  18. the most frequently occurring score in a set of scores
  19. a descriptive research technique that records naturally occurring behavior as opposed to behavior produced in laboratory
    naturalistic observation
  20. definitions that specify how concepts can be observed and measured
    operational definitions
  21. an inactive, or inert, substance that resembles a experimental substance
  22. a technique ensuring that each participant in an experiment has an equal chance of being assigned to any of the conditions of the experiment
    random assignment
  23. a procedure guaranteeing that everyone in population has an equal likelihood of being selected for the sample
    random sampling
  24. the difference between the largest and the smallest scores in a distribution
  25. when behavior changes as a result of the observation process
  26. a multi-step technique that generates empirical knowledge--that is, knowledge derived from systematic observations of the world.
    scientific method
  27. experimental participants do not know to which condition they have assigned (e.g., experimental versus control); its used to control for subject expectancies
    single-blind study
  28. an indication of how much individual scores differ or vary from the mean
    standard deviation
  29. a descriptive research technique designed to gather limited amounts of information from many people, usually by administering some kind of questionnaire.
  30. a measure of how the scores in a distribution of scores differ from one another
