Experimental Analysis

The researcher would like to investigate the influence of alcohol on driver reaction time. The respondents/drivers will be subjected to 'no-alcohol' condition during the first day and an 'alcohol' condition, in the following day. The measure of performance per day would be a driving simulation test to record the number of driving errors.

28.  What is the Independent Variable?

       a. Alcohol Conditioning      c . Performance per day

b. No Alcohol                    d. Driving Errors

29.  What is the Dependent Variable?    

a. Alcohol Conditioning      c . Performance per day
