10.2 Matched-Subjects Designs 1)The process of matching before assignment to conditions is called A)a pretest-posttest design. B)random participant assignment. C)nonrandom participant assignment. D)matched random assignment. 2)In matched-subjects designs, A)each participant is exposed to all levels of the dependent variable. B)each participant is exposed to one level of the dependent variable. C)each participant has a matched participant in each condition. D)each participant is exposed to all levels of the independent variable. 3)If strong carry-over effects are expected in an experiment, A)the within-subjects design is not recommended. B)the within-subjects design is recommended. C)controls for attrition are crucial. D)the problem statement for that particular study cannot be researched. 4)Which of the following is NOT a characteristic of matched-subjects designs? A)Each participant is exposed to only one level of the independent variable. B)Each participant has a matched participant in each of the other conditions, so that the groups are correlated. C)Each participant serves as his or her own control. D)The critical comparison is the difference between the correlated groups, where the correlation is created by the matching procedure. 5)Which of the following is true for within-subjects designs? A)There must be at least three conditions manipulated. B)Participants are all randomly assigned to conditions. C)Each participant serves as his or her own control. D)They require more participants than do between-subjects designs. 6)In matched-subjects designs, A)each participant is exposed to all levels of the independent variable. B)each participant is exposed to only one level of the independent variable. C)there must be at least three levels of the independent variable. D)there must be at least four levels of the independent variable in order to accomplish the proper matching. 7)In a research study employing a within-subjects design, the researchers become concerned that the hypothesis might be discernible by participants because each participant sees all of the experimental conditions. In such a circumstance, it would be best to use a A)time-series design. B)posttest-pretest design. C)matched-subjects design. D)single-subject design. 8)Independent-groups designs rely on ________ to equate groups. A)chance B)equivalence C)matching D)variable relevance 9)Matching participants A)becomes easier as the number of matching variables increases. B)increases error variance. C)is best when there are a small number of matching variables. D)requires equal numbers of males and females. 10)Matched-subjects designs are commonly used when A)we need an independent-subjects group. B)researchers are studying eye color or visual acuity. C)several dependent variables are being tested at the same time. D)exposure to a condition causes long-term changes in the participant, making it impossible for the participant to appear in the other conditions.Â
