Methods In Behavioral Research
(Chapter 10) Test Questions and
Answers
Discuss the role of simple main effects in interpreting interactions - Answer-Simple main
effect analysis examines mean differences at each level of the independent variable. If
the two lines are parallel, then you don't have an interaction but if they are, then you do
have an interaction.
Assignment of participants in an independent groups design - Answer-Different
participants are assigned to each of the conditions of the study. In a 2x2 study their will
be four groups.
Assignment of participants in a repeated groups design - Answer-the same individuals
are assigned to ALL conditions of the study.
Assignment of participants in a mixed factorial groups design - Answer-A combination of
independent groups design and repeated measure groups design.
Interaction effects on factorial design - Answer-Interaction effects means that the effect
of one independent variable has on a dependent variable depends on the level of the
other independent variable.
Participant Variables - Answer-Personal attributes such as age, sex, ethnic groups,
personaility types,
Factorial Design - Answer-more than one independent variable
Reasons to use factorial designs - Answer-1. Increasing the number of independent
variables is closer to real world conditions.
2. More than one level of the independent variable is needed in order to provide a more
accurate description of the relationship between the IV and DV.
3. An experimental design with only two levels of the IV cannot detect curvilinear
relationships between variables.
4. researchers are often interested in comparing more than two groups.
Describe the information provided by main effects in a factorial design - Answer-Main
effects is the effect of each independent variable taken by itself.
Describe an IV x PV Design - Answer-1. Includes both experimental (manipulated) and
nonexperimental (measured or nonmanipulated) variables.
2. Independent variable x participant variables.
