Question
A researcher was interested in the effects of 1) alcohol consumption and 2) content of a videotape, on how likely one is to support rape myths. The researcher randomly assigned 60 college-aged males to one of the following three groups: no alcohol consumed, a moderate amount of alcohol consumed, and a large amount of alcohol consumed. Additionally, half of the participants were shown the educational video on rape myths. The other half of the participants watched a documentary on owls (a control condition). At the end of the study all the participants filled out a survey on rape myth acceptance. Higher scores on the survey indicated higher acceptance of rape myths.
The results indicated that the participants who watched the educational video scored significantly lower on the rape myth scale compared to the group that watched the owl video. What does this suggest?
How many cells does this experiment have?
What type of statistical analysis would be most appropriate for this experiment?
What would you suggest if the researcher found that alcohol consumption increased rape myth acceptance, but only when the participants had watched the owl video?
There is a main effect of alcohol consumption.Explanation / Answer
a) It is talking of only one indepenndent variable, so it is not about an interaction
There is a main effect of video type.
b) since there are 2 variables 1) alcohol consumption and 2) content of a videotape with 3 and 2 levels repectively, cells or combinations = 3*2 = 6
c) a factorial analysis of variance
The factorial ANOVA doesn't only compare differences but also assumes a cause- effect relationship; this infers that one or more independent, controlled variables (the factors) cause the significant difference of one or more characteristics.
d) This is talking about the interaction between 2 independent variables.
There is an interaction between alcohol consumption and video type.
