Part I: Complex Experimental Designs In a study by Chaiken and Pliner (1987), research participants read an "eating diary of either a male or female person. The information in the diary indicated that the person ate large meals or small meals. The participants did not know the gender of the diary writer. After reading the diaries, participants rated the writer's femininity and masculinity on separate scales. 1. 3. Identify the design of this experiment. How many experimental conditions are in this experiment? Identify the independent variable(s) and dependent variable(s). Is there a subject variable in this experiment? If so, identify it. If not, can you suggest a subject variable that might be included? In the above study, the researchers reported the following mean femininity ratings (i.e. higher numbers indicate greater femininity): male - small meals (2.02) male - large meals (2.05) female - small meals (3.90) female - large meals (2.82) Assume that there are equal numbers of diary writers in each experimental condition. Calculate the data (show your work) and answer the following questions: 1. 2. 3. Are there any main effects of the independent (or subject) variables? Is there an interaction (AXB) between the independent (or subject) variables? Graph the means to determine if there is an interaction. Describe and interpret the results of your data analysis (#2.a-c above) in a brief paragraph.
