PSYCH 300
In this study researchers were interested in testing the hypothesis that people are less likely to hold others responsible for negative behavior when they are under the influence of alcohol. Participants were randomly assigned to consume one of three doses of alcohol: high, low, or none. Participants then read a scenario in which a male character sexually assaulted a female character. Participants rated the male character’s responsibility for his behavior on a scale ranging from 1 (not at all responsible) to 20 (completely responsible). Refer to the following computer output to answer the questions below:
A) What kind of research design was used here? How do you know?
B) Is this a true experiment? How do you know?
C) Name the independent variable and identify the scale of measurement for the IV.
D) Note that the description does not include a good operational definition for the IV. Pretend that you are the experimenter for this study. How would you operationally define the IV for this study as it is described in the question (don’t change the IV or the levels, just give them an appropriate operational definition)?
E) Name the dependent variable and identify the scale of measurement for the DV.
F) Did the IV have a statistically significant effect on the DV? How do you know?
G) Write a complete statistical conclusion for these results using proper APA style (just like you did for ID4).
