Design an Experimental Study

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?

This resource describes the atrocities that characterized the Tuskegee Syphilis Experiment. It was a defining study in history that highlighted ethical issues

concerning the treatment of human subjects during the conduct of experimental trials. Numerous government regulations and ethical considerations intended to protect

human subjects have been developed in part as a consequence of this study.

Order Description

To complete this exercise, you’ll need to have read about simple random sampling and how to use a table of random numbers (Babbie, pp. 220-222).

Visit the website http://www.ssa.gov/oact/babynames/. In the box titled “Popular Names by Birth Year,” enter the year 1900, and select the Top 100 names, then click

Go. You will see lists of the 100 most popular male and female names from people born in 1900. From each of those two lists, select a simple random sample of five

names, using the random number table as instructed on pages 220-222. Then describe the steps you took to create your samples.

A. SAMPLE OF MALES’ NAMES SELECTED:

1.

2.

3.

4.

5.

B. SAMPLE OF FEMALES’ NAMES SELECTED :

1.

2.

3.

4.

5.

C. Describe what you did to generate these samples.

Required Source ONLY:
Chapters 8 and 7 in Earl Babbie, The Basics of Social Research, 6th ed. Wadsworth, 2014. ISBN 113359414X

Responses will consistently demonstrate that the learner is reading/viewing the source material, reading others’ posts, and reflecting upon all of these, through

relevant responses. Responses will consistently draw on specific information from source material (e.g., videos, readings), using multiple specific, accurate, and

relevant examples. Responses are well organized, with no run on paragraphs or stream of consciousness writing. Use full sentences with proper grammar and almost no

spelling or punctuation mistakes. The tone of your response should reflect formal writing (e.g., no abbreviations that are better suited to informal texting, email, or

IM).
