  1. Survey Research
    A research study that uses the survey observational technique to measure behavior
  2. Psychometrics
    Area of psychological research that involves the development, validation and refinement of survey and tests to measure psychological constructs.
  3. Descriptive vs. Predictive
    Descriptive~A research question that asks about the presence of behavior, how frequently it is exhibited, or whether there is a relationship between different behaviors.

    Predictive~ A research question that asks if one behavior can be predicted from another behavior to allow predictions for future behavior.
  4. Causal Research Question
    A research question that asks what causes specific behaviors to occur
  5. Open-Ended vs. Close-Ended
    Close-ended~ participants respond to survey questions according to the response options provided by the researcher

    Open-ended~Participants respond to survey questions in any manner they feel is appropriate for the question.
  6. Construct Validity
    Indicates that a survey measures the behavior it is designed to measure
  7. Nonresponse Error
    A sampling error that occurs when individuals chosen for the sample do not respond to the survey, biasing the sample.
  8. Coverage Error
    A sampling error that occurs when the sample chosen the complete a survey does not provide a good representation of the population.
  9. Criterion-Related Validity
    Determining the validity of the scores of a survey by examining  the relationship between the survey scores and the other established measures of the behavior of the interest.
  10. Test-Retest Reliability
    Indicates that the scores on a survey will be similar when participants complete the survey more than once.
  11. Attrition/mortality
    Occurs when participants choose not to complete a study
  12. Testing effects
    Occur when participants are tested more than once in a study, with early testing affecting later testing.
  13. Internal Consistency
    A form of reliability that tests relationships between scores on different items of a survey.
  14. Split-Half Reliability
    Method of testing scores' internal consistency that indicates if the scores are similar on different sets of questions on a survey that address similar topics.
  15. Cronbach's Alpha
    A method of testing scores' internal consistency that indicates the average correlation between scores on all pairs of items on a survey
  16. Predictor variable
    the dependent variable in a correlational study that is used to predict the score on another variable
  17. Outcome variable
    The dependent variable in a correlational study that is being predicted by the predictor variable
  18. Third variable problem
    The presence of extraneous factors in a study that affect the dependent variable and can decrease the internal validity of the study
  19. Pearson R
    A significance test used to determine if a linear relationship exists between two variable measured on interval or ratio scales.
  20. Positive vs. Negative relationships
    Positive~ A relationship between variables characterized by an increase in one variable that occurs with an increase in the other variable.

    Negative~ A relationship between variables characterized by an increase in one variable that occurs with a decrease in the other variable.
  21. Quasi-experiment
    A type of research design where a comparison is made, as in an experiment, but no random assignment of subjects to groups occurs
  22. Random Assignment
    Participants are randomly assigned to levels of the independent variable in an experiment to control for individual differences as an extraneous variable.
  23. Pretest-Posttest Design
    A type of research design (often a quasi-experiment) where behavior is measured both before and after a treatment or condition is implemented.
  24. Nonequivalent groups
    Groups compared in a study where participants are not randomly assigned.
  25. Regression (toward the mean)
    Can occur when participants score higher or lower than their personal average-the next time they are tested, they are more likely to score near their personal average, making scores unreliable.
  26. history effects
    Events that occur during the course of a study to all participants or to individual participants that can result in bias.
  27. Testing effects
    occur when participants are tested more than once in a study, with early testing affecting later testing.
  28. Solomon Four Group Design
    Pretest-Posttest design with two sets of nonequivalent groups in which one set takes the pretest and posttest and one set takes only the posttest.
  29. Time Series Design
    A research design in which patterns of scores over time are compared from before a treatment is implemented and after a treatment is implemented.
  30. Maturation
    Natural changes that occur to the participants during the course of a study that can result in bias.
  31. Longitudinal Design
    A developmental design where a single sample of participants is followed over time and tested at different ages.
  32. Cross-Sectional Design
    A developmental design in which multiple samples of participants of different ages are tested once.
  33. Cohort sequential design
    A developmental design where multiple samples of participants of different ages are followed over time and tested at different ages.
  34. Generation (Cohort) effects
    A confound that can occur in cross-sectional designs due to different experiences that different generations have.
  35. Small n design
    An experiment conducted with one or a few participants to better understand the behavior of those individuals
  36. Baseline measurement
    A small n design that involves baseline measurements of behavior as compared with measures of behavior during the implementation of a treatment.
