Discussion
Ideally, the variables present in an experimental study can be controlled. There are also many other issues to consider when designing an experimental study.
In this Discussion, you will propose a design for an experimental study and identify some of the issues that could arise as a result of the design. You will then be asked how you would mitigate, or minimize, those issues.
To prepare for this Discussion:
Refer to the public health problem you selected last week. Or, choose another public health problem that interests you.
Determine a research question for the study.
Based on the research question, consider how you would design an experimental study.
Post a comprehensive response that proposes an experimental study design for your chosen topic. Your contribution should take into account at least two of the following factors:
Informed consent
Special populations
Blinding
Incentives for volunteers
Closing a study early
Your post should also answer the following questions.
What is the research question for your study?
What exposure and outcome variables will you measure?
Who will be the participants?
How is the method for this week's study different from the method for last week's study?
