10.1 Within-Subjects Designs 1)At least two levels of a manipulated independent variable are necessary in A)case-study research. B)naturalistic research. C)experimental research. D)differential research. 2)Correlated-groups designs A)use random assignment of participants. B)provide equivalent groups at the start of the study. C)use only one level of the independent variable. D)are less sensitive than between participant experimental design. 3)Correlated-groups designs A)test causal hypotheses with randomization. B)test causal hypotheses without eliminating rival hypothesis. C)are more sensitive to the effects of the independent variable than are between-subjects designs. D)are more sensitive to the effects of the dependent variable than are between-subjects designs. 4)Why do the authors of this text consider correlated-groups designs to be experiments? A)They maximize error variance. B)They always use score data. C)They randomly assign all participants to conditions. D)They meet the requirement of equivalence of groups. 5)Which of the following is NOT used in correlated-groups designs? A)Matching of participants. B)Random assignment to conditions. C)Within-subjects procedures. D)Careful measurement of the dependent variable. 6)In randomized, between-subjects experimental designs, each participant is A) exposed to only one level of the independent variable. B)exposed to several levels of the independent variable. C)matched with one other participant. D)a member of one of at least two correlated groups. 7)Which of the following is NOT a characteristic of a randomized, between-subjects experimental design? A)Each participant is exposed to more than one level of the independent variable. B)The groups are independent of each other. C)Only one score per participant on the dependent variable is used in analyzing the results. D)The critical comparison is the difference between independent groups on the dependent measures. 8)Random assignment of participants to conditions gives us confidence that A)the researcher will remain blind to the condition under which each participant is tested. B)the groups to be compared are equivalent at the start of the study. C)the participants will remain blind to condition throughout the experiment. D)any placebo effect will be nullified. 9)Within-subjects designs allow a researcher to test causal hypotheses with confidence and without A)mistakes. B)statistical analyses. C)randomization. D)any form of bias. 10)Correlated-groups designs are generally more sensitive than between-subjects designs to A)researcher effects. B)the effects of the dependent variable. C)medications. D)the effects of the independent variable.Â
