65. 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) we shall use ONE WAY ANOVA here. the data matches with the one way layout so we are using this

C) independent variables are levels of alcohol. dependent variable is scale ranging

B) yes it is true experiment, as it satisfies all the criteria of true expreiment

There are three criteria that must be met in a true experiment
