  3. What two concepts are relevant to non-experimental study design?
    • control
    • bias
  4. What is the term for a cause-and-effect relationship between interrelating variables? There are multiple independent variables causing a change in the dependent variable.
    multicausality
  5. What is the term for the chance that something will occur under a defined set of circumstances?
    probability
  6. What is the downside of control?
    the findings are less generalizable
  7. What is the term for the slanting of findings away from the truth?
    bias
  8. What is the term for what is used to exert control by allowing only participants with defined characteristics to participate in the study?
    eligibility criteria
  9. What type of non-experimental design examines characteristics of a single sample, identifies phenomenon, variables, conceptual, and operational definitions and describes definitions?
    typical descriptive design
  10. What type of non-experimental design examines differences in variables in two or more groups that occur naturally in a setting?

    descriptive correlational design
  13. What type of non-experimental design predicts value of one variable (dependent variable) based on values obtained for other (indepedent variables)?
    predictive correlational design
  14. What type of non-experimental design involves the exploration of single unit of study (i.e. family, group, or community) and two groups are studied at the same time?
    case control
  15. What type of non-experimental design involves following a group of participants longitudinally over a period of time to describe the incidence of a problem or to determine the relationship between a predictor variable and an outcome?
    cohort study
  16. What type of study looks over a period of time (several time points)?
    longitudinal
  17. What type of study looks at one period in time?
    cross-sectional
