QUESTION 6 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, 2 ounces of alcohol, 4 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 curvy road and a road with obstacles. Course completion times were recorded for each participant. Respond to the following five items in order. Be sure to label your responses a, b, c etc. a.) Identify the design (be specific; e.g., 2 x 2 repeated measures factorial design) (2pts) b.) Identify the independent variable(s) (.5 pt) c.) ldentify the dependent variable(s) (.5 pt) d.) Identify possible main effects (1pt) e.) Identify any possible interactions (1 pt)Explanation / Answer
Question 6:
A. This is an example of a 4 x 3 between groups factorial design. This is because there are four levels of alcohol consumption and 3 levels of driving conditions. It also involves individuals in separate groups, thereby making it a between groups design.
B. Alcohol consumption and road conditions, as the effect of two variables are being studied by the researchers by introducing different levels of the same.
C. Night driving reaction is the dependent variable, as this is the phenomenon of that is being studied by the researcher for which the aforementioned variables are being manipulated.
D. The main effect could be differences in driving reactions due to alchol consumption and/or road conditions.
E. An interaction effect could occur between alcohol consumption and road conditions.
