Document Content and Description Below

Darley and Batson conducted a study in which the independent variable was the degree to which the participants were instructed to hurry to the other building (high-hurry, intermediate-hurry, low-hurry... ) and the dependent variable was the amount of help offered to a “victim” placed by the researchers between the two buildings. This was a between subjects design. Therefore, how many groups of participants were needed? • Question 3 2 out of 2 points Betsy is conducting a study on school psychologists. She is thinking of having school psychologists complete four experimental conditions each lasting one hour. A colleague suggests to Betsy that she modify the design so that different groups of school psychologists are used and Betsy will not have to worry about __________. • Question 4 2 out of 2 points During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During the challenge, participants were asked to taste cola from both Coke and Pepsi. Once they had tasted both drinks, the participants were asked to report which was better tasting. The results indicated that participants found Pepsi products to be better tasting. This is an example of what type of research design? • Question 5 2 out of 2 points The degree of spread among data surrounding the mean is known as _____________. • Question 6 2 out of 2 points While conducting her within subjects design, Geraldine notices that participants are failing to fully complete the last level of the independent variable. Specifically, subjects are leaving questions blank and do not appear to be placing as much effort into the study as they were in the first level of the independent variable. Geraldine is seeing what disadvantage to using a within subjects design? • Question 7 2 out of 2 points _________ occurs when the effects of a prior condition influence subsequent treatment conditions. • Question 8 2 out of 2 points During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During the challenge, participants were asked to taste cola from both Coke and Pepsi. Once they had tasted both drinks, the participants were asked to report which was better tasting. The results indicated that participants found Pepsi products to be better tasting. What is the dependent variable in this study? • Question 9 2 out of 2 points To combat order effects that may occur with a within subjects design, many researchers will use _____________. • Question 100 out of 2 points We discussed a study known as the Stroop effect. Stroop developed 3 types of stimuli for his study. Each type of stimuli presented a different task that participants had to complete. Stroop then measured the amount of time it took the participants to complete each task. What is the dependent variable in this study? • Question 11 2 out of 2 points Tamir et al. (2008) conducted a study to see what impact music has on participants playing computer games. The researchers had participants play computer games while listening to angry, exciting, and neutral music. The researchers then measured the participant’s performance while listening to each type of music. How many levels are there to the independent variable in this study? • Question 12 0 out of 2 points During the late 1980s and the early 1990s the Pepsi Challenge was in full swing. During the challenge, participants were asked to taste cola from both Coke and Pepsi. Once they had tasted both drinks, the participants were asked to report which was better tasting. The results indicated that participants found Pepsi products to be better tasting. What is the independent variable in this study? [Show More]
