Researchers investigated factors that influenced how much people like each other based on first meeting. They were particularly interested in the effects of eye-to-eye contact and smiling. They collected data from 20 participants. Each participant was asked to wait in a small room while the experimenter went next door, ostensibly to gather the materials needed for the study. While the participant was waiting, a confederate of the experimenter entered the room and sat in a chair facing the participant, and asked "Are you waiting for the experiment?". Immediately after asking the question, the confederate smiled at, and/or looked directly into the eyes of, the participant. This was done in four conditions: for five participants the confederate smiled and looked into the participant's eye, for five participants the confederate smiled but did not look into the participant's eye, for five participants the confederate did not smile but did look into the participant's eyes, and for five…
W. Thomas Boyce, a professor and pediatrician at the University of British Columbia, Vancouver, has studied interactions between individual differences in physiology and differences in experience in determining health and well-being. Dr. Boyce found that some children are more sensitive to their environments. They do exceptionally well when the environment is supportive but are much more likely to have mental and physical health problems when the environment has challenges. You decide to do a similar study, conducting a factorial experiment to test the effectiveness of one environmental factor and one physiological factor on a physical health outcome. As the environmental factor, you choose two levels of stressful life events. As the physiological factor, you choose three levels of immune reactivity. The outcome is number of respiratory illnesses in the previous 12 months, and the research participants are kindergartners.
In an experiment with two factors, A and B ,what is the purpose of doing a multiple comparison if a. only the Factor A effect is significant? b. both Factor A and B effects are significant, but the interaction is not? c. the interaction between A and B is significant?
