Dashboard Find the mean, median, and mode for the scores in the following frequency distribution table: x 6 1 5 2 4 2 3 2 2 2 1 5 Schmidt (1994) conducted a series of experiments examining the effects of humor on memory. In one study, participants were shown a list of sentences, of which half were humorous. A humorous example is, "If at first you don't succeed, you are probably not related to the boss." Other participants would see a non-humorous version of this sentence, such as "People who are related to the boss often succeed the very first time." Schmidt then measured the number of each type of sentence recalled by each participant. The following scores are similar to the results obtained in the study. Humorous Sentences: 4 1 5 4 5 3 2 5 4 5 6 Non- Humorous Sentences: 7 3 6 1 6 6 2 3 5 2 4 3 3 3 2 1 4 5 2 2 3 Calculate the mean number of sentences recalled for each of the two conditions and compare the means to each other. Do the data suggests that humor helps memory? Explain. Stephens, Atkins, and Kingston (2009) conducted a research study demonstrating that swearing can help reduce pain. In the study, each participant was asked to plunge a hand into icy water and keep it there as long as the pain would allow. In one condition, participants repeatedly yelled their favorite curse words while their hands were in the water in other condition the participants repeated a neutral word. Does similar to the results obtained in the study are shown in the following table. Calculate the mean number of seconds that the participants could tolerate the pain for each of the two treatment conditions. Does it appear that swearing helped with pain tolerance? Explain. Participants Swear Neutral Words Words 1 2 3 4 5 6 7 8 9 10 94 70 52 83 46 117 69 39 51 73 59 61 47 60 35 92 53 30 56 61 Earlier in this chapter (p.67), we mentioned a research study demonstrating that alcohol consumption increases attractiveness rating for members of the opposite sex (Jones, Jones, Thomas, & Piper, 2003). In the actual study, college age participants were recruited from bars and restaurants near campus and asked to participant in a "market research" study. During the introductory conversation, they were asked to report their alcohol consumption for the day and were asked to report their alcohol consumption for the day were told that moderate consumption would not prevent them from taking part in the study. Participants were then shown a series of photographs of male and female faces and asked to rate the attractiveness of each face on a 1-7 scale. The following data duplicate the general pattern of results obtained in the study. The two set of scores are attractiveness ratings for one female obtained from two groups of males: those who Calendar To Do Notifications Inbox
