1. Explain Experimental Effects Suppose you wanted to study the effect of advertising appeals (individualistic vs. collectivistic) on purchase intentions and reveal how the effect may differ between two different cultures: U.S. and China. One hundred U.S. consumers were recruited and randomly assigned to view an ad with either individualistic or collectivistic appeals. The same procedure was performed among 100 Chinese consumers, too. After the subjects were exposed to the assigned advertising appeals, they were asked to rate “how likely they would purchase the product in thead?” on a 10-point scale, with “1” being “not likely” and “10” being “very likely.” The average ofpurchase intention scores for each condition was reported in the table below.What is the experimental or independent variable?The cultural variable (U.S. vs. China) is considered as a _______ variable. (What is the dependent variable? Is there a main effect? If yes, describe at least one Is there an interaction effect? If yes, describe it. What’s the purpose of random assignment in this experiment? Be specific
