MULTIPLE-CHOICE QUESTIONS 8-1) Which of the following does not represent one of the criteria for deriving a cause-effect conclusion in experimental research? a. Covariation of variables b. Causal time sequence c. Results analyzed with ANOVA d. Elimination of other plausible causes 8-2) In experimental research, when the same participants are subjected to all levels of the independent variable, the design is based on a a. repeated-measures design. b. within-subjects design. c. both a and b d. neither a nor b 8-3) In repeated-measures designs, when studies utilize techniques that meet the three criteria of cause-effect conclusions, the designs are considered a. controlled within-subjects designs. b. quasi-experimental within-subjects designs. c. interrupted time-series designs. d. between-subjects factorial designs. 8-4) Sometimes researchers make use of within-subjects designs where they cannot create equivalent groups or directly manipulate an independent variable. In this case, the researchers are using a within-subjects, __________ design. a. between-subjects b. quasi-experimental c. correlational d. descriptive 8-5) Which of the following is not an example of a quasi-experimental, within-subjects research design? a. Longitudinal design b. One-group pretest-posttest design c. Interrupted time-series design d. Between-subjects factorial design 8-6) Which of the following quasi-experimental within-subjects research designs represents the strategy of testing the same individuals repeatedly over a long period of time, and age of the subjects represents the independent variable? a. Longitudinal design b. One-group pretest-posttest design c. Interrupted time-series design d. Between-subjects factorial design 8-7) Which of the following quasi-experimental within-subjects research designs represents the strategy of taking a series of measurements on the same individuals before and after an event or treatment occurs, and the time frame relative to the event represents the independent variable? a. Longitudinal design b. One-group pretest-posttest design c. Interrupted time-series design d. Between-subjects factorial design 8-8) Dr. Ryan is working on a study where he has subjects complete an intelligence test and, based on their scores, he attempts to equate three different experimental groups by randomly assigning those with relatively high scores to each of the three groups. This design is referred to as a a. longitudinal design. b. matched-subjects design. c. interrupted time-series design. d. one-group pretest-posttest design 8-9) To carry out a matched-subjects design, researchers must a. utilize each matching variable and have access to a reliable and valid way to assess it. b. measure the matching variable and establish groups of subjects who are similar on that     variable. c. randomly assign subjects from each set to the appropriate experimental groups. d. all of the above 8-10) Professor Matthews is carrying out a within-subjects experiment where she is administering to her participants a list of words to memorize and, in the second condition, after a 10mg dose of caffeine, she administers the same list of words to memorize. She is worried that the sequence of the words on the list might interfere with her ability to interpret whether or not caffeine affects one’s ability to memorize. Based on this description, it appears that Professor Matthews is concerned about a potential __________ in her research design. a. order effect b. independent variable c. interrupted time-series d. placebo effect 1
