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.

• choose a 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?

****Last weeks study was an Observation Study****
