Astudy placed strangers in pairs and asked them to talk together following a series of instructions designed to them become close. at the end of 45 minutes, individuals privately answered some questions about how close they now felt to their partners. (the researchers combined the answers into a "closeness composite.") one key question was whether closeness would be affected by either (a) matching strangers based on their attitude agreement or (b) leading participants to believe that they had been put together with someone who would like them. the result for both agreement and expecting to be liked was that "there was no significant differences on the closeness composite." the researchers went on to argue that the results suggested that there was little true effect of these variables on closeness. an excerpt has been linked below. explain this result to a person who understands hypothesis testing but has never learned about power or effect size
