Amit Almor, a psychology researcher at the University of South Carolina, conducted a series of experiments on conversation and attention level. He found that subjects were four times more distracted while preparing to speak or speaking than when they were listening. This research has implications for the issue of using cell phones while driving, as well as for many other areas. You decide to explore this issue by having three different groups try detecting visual shapes on a monitor. The first group is preparing to speak, the second group is speaking, and the third group is listening to a conversation. The sample mean and sum of squares of the scores for each of the three groups are presented in the following table. Group Preparing to speak Speaking Listening After collecting the data, you analyze the data using an ANOVA. The results of your analysis are presented in the following ANOVA table.
