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.

Solution

a)a one-way x2-goodness of fit design is useful here as we want to predict or check any kind of relationship between influence of alcohol and negative behaviour.( or can be used like a contingency table!and then a exact test! where is tthe computer output mentioned in the ques!? )

b) yes! here is control group i.e the \"none\" , experimental groups i.e, \" low\" and \" high\" and researcher manipulated variable which is the responsibility ratings!and , each participants has equal chances of getting into any groups!

c) independent variable is influnce of alcohol! and it\'s dependant variable is \" negative behaviour\" ( and how they are realted is the agenda of testing! )
