Scenario:
What makes a person a “leader”? A social psychologist hypothesizes that the extent to which people are perceived to be leaders is positively related to the amount of talking they do, regardless of what they are actually saying. She conducts an experiment in which groups of participants solve a problem together. One of the participants in each group is a confederate who speaks a different number of sentences for different groups, half of which are designed to help the group solve the problem and half are not helpful. Following the group work, the confederate is rated by the other participants on his or her leadership ability (1=low, 10=high). The following data represents the findings of this fictional researcher.
