| Question | Answer |
| Types of survey data collection methods | Self-administered Telephone In person |
| Questionnaires include | Questions and statements |
| Response categories/response options refer to... | The list of possible answers to a question or statement. |
| Open-ended questions | Respondent provides own answer to questions |
| Closed-ended questions | Respondent answers are limited to the list provided by the researchers |
| Survey | Does not establish cause and effect (disadvantage) independent variable is measured as it occurs naturally (advantage) |
| Experiment | Establishes cause and effect (advantage) Independent variable is manipulated (Is artificial) (disadvantage) |
| Response rates and cost for: In-person, telephone, self-administered | In-person has highest response rate, is most expensive Self-administered has lowest response rate, is least expensive |
| Exhaustive response questions... | Include all possible responses that might be expected (closed-ended questions) |
| Mutually exclusive response questions... | No more than one category should apply to a respondent (closed-ended questions) |
| Contingency questions | Whether or not contingency questions are asked (is contingent on) the responses to a different question |
| Matrix questions | A set of questions that share answer choices (ex: extremely important, important, somewhat important, somewhat unimportant, unimportant). Ideal when several questions or statements have the same response categories |
| Response rate | # of people who participate (divided by) the number of eligible people in the sample (denominator includes people who couldn't get ahold of, people who refuse, and people who participate) |
| Importance of double-blind in experiments | (Neither the subject nor the experimenters know who is in the experimental group and who is in the control group) |
| Pretest sensitization | Changes in the experimental group due to the pretest and not the treatment. (Ex: drug users fill out a pretest questionnaire that makes them feel bad about their drug use and they change their behavior based on that, not the treatment) |
| Importance of monitoring returns in survey research | The higher the |
| What does CATI stand for? | Computer assisted telephone interviewing |
| Form used to monitor outcome of every call or attempted contact during a telephone survey | Disposition sheet |
| Importance of a return-rate graph for monitoring returns | You can see what percentage of eligible people actually participate |
| 1 main advantage and 1 main disadvantage of experiments | Advantage - can determine cause and effect Disadvantage - Artificiality |
| External validity | Refers to the possibility that the conclusions drawn from experimental results may not be generalizable to the “real” world. |
| 5 sources of internal validity | History Maturation Testing Selection bias Demoralization |
| 3 ways of selecting subjects | Randomization Probability sampling Matching (pairs are matched and assigned to experimental and control groups) |
| Difference between random sampling and randomization | ?? |
| Source of internal validity: History | ?? |
| Source of internal validity: Maturation | ?? |
| Source of internal validity: Testing | ?? |
| Source of internal validity: Selection bias | ?? |
| Source of internal validity: Demoralization | ?? |
| Procedure to theoretically ensure the treatment group and control group are similar | Matching |
