A scientist is studying the effects of alcohol on driving ability. Set up an experimental design in which this scientist could identify the effects of alcohol on driving ability. In your description, be sure to label your hypothesis, the independent variable, the dependent variable, the control group, and the experimental group. How could this scientist avoid the effects of experimenter bias when scoring the results of the study?

(Answers may vary) In this experiment, a driving simulator could be used to determine how a control group (individuals who did not receive any alcohol before the experiment) performed compared to an experimental group (that was given a beer to drink before going in the driving simulator). In this study, it is hypothesized that the group given a beer would have slower reaction times to stop signs and lights, as a result of the alcohol they drank before being in the simulator. To avoid experimenter bias, the experiment could be blind such that the researcher did not know if they were measuring stop times for someone in the control or experimental condition.
