Chapter 11 Correlated-Groups and Single-Subject Designs
11.1 Within-Subjects Designs
1) 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.
Answer: B
Type: MC

2) 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.

4) Random assignment of participants to conditions gives us confidence that

- 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.

10) What is the major strength of the within-subjects design?
- A) More participants can be used in a single study.
- B) Interactive effects can be identified.
- C) Carry-over effects are eliminated.
- D) It guarantees that the participants in the various conditions are equivalent at the start of the study.
Answer: D
Type: MC

11) In which design are all participants exposed to all experimental conditions?
- A) randomized, posttest-only
- B) randomized, pretest-posttest
- C) within-subjects
- D) between-subjects
Answer: C
Type: MC

12) A within-subjects design helps to ensure equivalence of groups at the start of the experiment because
- A) it employs a form of randomization.
- B) the participants in one group are the same participants as in the other group.
- C) of the extensive pretesting to rule out differences between individuals.
- D) of the stringent criteria of participant selection.
Answer: B
Type: MC

13) In order to test the effects of noise levels on typing speed, a researcher uses six expert typists and asks each to type a page at two different noise levels (low and high). The dependent variable, typing speed, is measured under both conditions for all typists. What kind of design is the researcher employing?
- A) a between-subjects design
- B) a between-groups design
- C) a within-subjects design
- D) a single-variable, independent-groups design
Answer: C
Type: MC

Skill: Applied
14) A within-subjects design is also referred to as a(n)
- A) between-subjects design.
- B) independent-groups design.
- C) nonparametric design.
- D) repeated-measures design.
Answer: D
Type: MC

15) The key idea in correlated-groups designs is that in seeking to insure equivalence of groups,
- A) some correlation among participants in different groups is introduced.
- B) there is no correlation introduced in the assigning of participants to groups.
- C) a small participant size must be used to prevent error.
- D) coefficients of correlation must be group specific.
