Exam 3 Flashcards
Mixed and nested designs both
A) mix experimental and correlational variables in the same experiment.
B. compare the results from between-subjects experiments to those of separately
conducted within-subjects experiments.
C. mix multiple independent variables with multiple dependent variables in the same
experiment.
D. mix between-subjects and within-subjects manipulations in the same experiment.
v
Which of the following designs allows you to mix within-subjects and between-subjects components? A. a mixed design B. a nested design C. a combined design D. both a and b
v
Two groups of subjects are exposed to different levels of Factor A. Within each group, all
subjects are exposed to the same two levels of Factor B. This is a _____________ design.
A. combined
B. Latin square
C. mixed
D. nested
v
The following design is a ________ design.
A1 A2
B1 B2 B3 B4
A. combined
B. Latin square
C. mixed
D. nested
v
You include a set of four tasks under one level of your independent variable, and a
different set of four tasks under the other level. Your experimental design is a ________
design.
A. completely counterbalanced
B. Latin square
C. Nested
D. combined
v
Including a covariate in your design allows you to
A. subtract the influence of a variable from your dependent variable.
B. include multiple quasi-independent variables in the same experiment.
C. add the influence of a covariate to your independent variable.
D. none of these
v
A major disadvantage of including a quasi-independent variable in an experiment is that
A. carryover effects are an even bigger problem than in a standard within-subjects
design.
B. results are difficult to analyze statistically.
C. results are often misinterpreted as being “causal”.
D. the resulting design cannot be carried out easily.
v
Including a quasi-independent variable in your research allows you to
A. test the generality of your findings across the levels of the quasi-independent
variable.
B. reduce error variance by segregating the data into groups of participants who
responded in similar fashion to the manipulation.
C. analyze within-subjects and between-subjects factors in the same design.
D. both a and b
v
You have six different classes available for your experiment. You expose the first three classes to one level of your independent variable and the remaining three classes to the other level. In this experiment, you are A. counterbalancing class across treatments. B. nesting classes under levels of your independent variable. C. using class as a correlational variable. D. none of these
v
