Mariah wants to study the effects of arousal and cost on helping behavior. She has two experimental conditions of high versus low arousal, and combines that with two experimental conditions with high and low cost of helping. This creates four possible conditions: high arousal/high cost, high arousal/low cost, low arousal/high cost, and low arousal/low cost. She then measures which condition results in the highest rate of helping behavior. Mariah has employed ____.
A) a factorial design
B) a meta-analysis
C) a correlational approach
D) mundane realism

Question

Quizplus · Accepted Answer

Mariah has employed a factorial design, which involves manipulating two or more independent variables in a single study to examine their joint effects on the dependent variable. In this case, the independent variables are arousal level and cost of helping, and the dependent variable is the rate of helping behavior. By creating four different experimental conditions, Mariah can determine the relationship between these two independent variables and the resulting level of helping behavior.
