Question
Participants participated in a driving simulation study to investigate night-driving reactions as a function of alcohol consumption and road conditions. Participants drank “cocktails” containing either no alcohol, 3 ounces of alcohol, or 6 ounces of alcohol. After 30 minutes, they began the driving simulation test. Each participant simulated a drive on a straight road, a road with gentle curves, or a road with many sharp curves and on which the participants encountered various road hazards. Driving speed and the number of accidents were measured.
Identify the design (e.g., 2 X 2 factorial).
Identify the total number of conditions.
Identify the manipulated variable(s).
Is this an IV X PV design? If so, identify the participant variable(s).
Is this a repeated measures design? If so, identify the repeated variable(s).
Identify the dependent variable(s).
Explanation / Answer
The nature of the roads that are being used are relatively many hence the number of conditions will be depend on the roads. Below are the results:
Final Solutions
1.(Not present)
2.Road conditions and alcohol consumption (independent variables)
3.Design is 3×3
4. N/A(not applicable)
5.9 is the total number of conditions
6.No. This is not a repeated measure design.
7.Driving speed and the number of accidents (dependent variable)
