Read the following scenario and design a simple study by addressing the requirements below. Submit your 1-page response as a
"Word Document."
A tobacco company wants to encourage the use of cigarettes and puts out an ad suggesting that nicotine may enhance reaction
time and therefore driving ability. Is there some truth to their suggestion since nicotine acts as a stimulant when bound to
receptors on muscle fibers? Design a simple study using the experimental research method to test the hypothesis that 'Nicotine
enhances driving ability! Your research design should answer the following questions by addressing the items below. This is only
an experiment "plan." Please do not collect data! :)
1. In your design description: Identify your sample or who you plan to study. Characteristics of the sample should be appropriate
for the variables under study (ie., should the study include people of all ages?... etc.)
2. Identify the independent variable (IV) and describe what your experimental group and control group will receive in terms of
the level of the IV. Describe how the IV will be administered to the groups.
3. Identify the dependent variable (DV) and describe what will be measured from your participants. Groups will be compared on
the DV to determine if the IV was effective.
4. List at least 3 control variables that you, as the researcher, should keep consistent across the two groups under study;
remember you want to treat the groups as similarly as possible and vary them ONLY on the IV so that any changes in the DV can
be attributed solely to the IV.



Answer :

Final answer:

Designing a study to test if nicotine enhances driving ability by examining the variables, treatments, participant selection, control variables, lurking variables, and blinding methods.


Explanation:

Explanatory variable: Nicotine

Response variable: Driving ability

Treatments: Experimental group receives nicotine, control group does not.

Participants: Select individuals with prior driving experience.

Control variables:

  • Driving route
  • Time of day
  • Vehicle type

Lurking variables: Previous nicotine exposure, caffeine consumption, stress levels.

Blinding: Participants blinded to their group assignment to reduce bias.
