Discussion Question (B)

Begin your discussion by sharing your problem statement and research question. Next, discuss your sampling plan. In addition, discuss your research design. Consider the following as you craft your response.

Sampling

• How will the sample be selected?
• What type of sampling method is used? Is it appropriate to the design?
• Does the sample reflect the population as identified in the problem or purpose statement?
• Is the sample size appropriate? Why or why not?
• To what population may the findings be generalized? What are the limitations in generalizability?

Research design

• What type of design will be used?
• Does the design seem to flow from the proposed research problem, theoretical framework, literature review, and hypothesis?

Discussion Question (C)

Please begin by responding to the following questions.

Search and locate an existing instrument that will be used to address your research question. Post the title of the instrument selected and the level of measurement on the tool. Next, post a description of the type of scale used in the instrument. Include a brief discussion of data collection procedures that will be presented in your proposal.
