Textbook Question
Chapter 15.4, Problem 32E
The behavior of undergraduate students when exposed to various odors was examined by the authors of the article “Effects of Environmental Odor and Coping Style on Negative Affect, Anger, Arousal and Escape” (Journal of Applied Social Psychology [1999]: 245–260). The following table was constructed using data on reported discomfort level (measured on a scale from 1 to 5). There were 24 students in each odor-sex combination. The entries in the table are the sample means for the 8 treatments.
- a. Construct a graph (similar to those of Figure 15.8) that shows the
mean discomfort level on the vertical axis. Mark the four odor categories on the horizontal axis. Then plot the four means for the males and connect them with line segments. Plot the four means for females and connect them with line segments. - b. Interpret the interaction plot. Do you think that there is an interaction between sex and type of odor?
