Differentiate probability and non-probability sampling, providing research examples to illustrate when probability sampling is appropriate and when non-probability sampling is appropriate.
Identify three types of probability sampling, explaining how each is performed.
Identify three types of non-probability sampling, explaining how each is performed.
Explain the strengths and weaknesses of probability and non-probability sampling in terms of how each does or does not reduce probability error and sampling bias.
Part 2: Research Challenges
Describe at least five challenges that may be encountered when completing research. As discussed in this week’s readings, these challenges may involve gatekeepers and access to data or subjects being denied for political, procedural, and/or ethical reasons.
Provide examples for each of the five challenges to support your discussion.
Explain how you could develop/alter the research design to overcome each of the five identified challenges.
Part 3: Ethical Research
Describe principles of ethical research, including policies and regulations that govern research involving human subjects.
Describe the Institutional Review Board process.
Discuss ethical considerations related to your proposed research study (the one that will form the basis of the preliminary research proposal you are completing for this course).
