C‌‍‍‍‌‍‍‌‌‍‍‍‌‍‍‍‍‌‍‍reswell and Creswell (2018) provide an overview of quantitative research in Chapter 8. You should particularly focus on pages 166–172 that discuss quantitative designs and threats to validity. A common issue that some people have is confusing Campbell and Stanley’s (2015) four broad types of research: experimental, quasi-experimental, pre-experimental, and nonexperimental. The key elements of these are clarified and differentiated in the Quantitative Research Design Concepts table. Another common issue is confusion regarding random sample and random assignment. These are also clarified and differentiated in the table. The Creswell and Creswell reading and the table, which summarizes key concepts of quantitative research, will prepare you for the Discussion. In this Discussion, you will identify an appropriate research design, sampling strategy, and research method that aligns to the quantitative research problem, purpose, research question, and theoretical framework you discussed in Weeks 1 and 2. To Prepare Read this week’s Learning Resources. Pay particular attention to the required elements of different quantitative designs, and reflect on examples of when you would use each. In addition, consider different quantitative sampling strategies and data collection methods. Review your Weeks 1 and 2 Discussions on a quantitative research problem, purpose, research question, and theoretical/conceptual framework. Identify an appropriate and specific quantitative research design, sampling strategy, and data collection method that aligns to your research problem, purpose, research question, and theoretical/conceptual framework. Alignment of scenario elements is important. See the Examples of Aligned and Misaligned Scenarios document, which can be downloaded from the Week 3 Learning Resources area of the classroom. Discussion posts are pass/fail but have min‌‍‍‍‌‍‍‌‌‍‍‍‌‍‍‍‍‌‍‍imum criteria to pass. See the Discussion Rubric to ensure you understand the pass/fail criteria. This week is only about the quantitative scenario. Repost, or build on or refine as needed, your Week 1 and Week 2 Discussion of your quantitative scenario using the following headings and according to the italicized instructions given for each element: Program of Study: Identify your specific program of study and, if applicable, your concentration area. Social Problem: Briefly describe the social problem or phenomenon of interest. Typically, this can be done in 3 or fewer sentences. Quantitative Research Problem: Complete the following sentence: The scholarly community does not know… Quantitative Research Purpose: Typically, this is a 1-sentence statement addressed by completing the following sentence: The purpose of this quantitative study is… Quantitative Research Question: Typically, this is a 1-sentence question unless you have more than one research question. Theory or Conceptual Framework: Identify a specific psychological or sociological theory or specific aspects of a conceptual framework that guides the scenario. Briefly describe how the specific theory or conceptual framework guides your research question and will aid in interpretation of results. Quantitative Research Design: Identify a specific quantitative research design. Do not use broad terms, such as survey design, cohort design, longitudinal design, causal-comparative design, cross-sectional design, and so on. Briefly describe how the selected design fits your scenario. If you have the Campbell and Stanley (2015) textbook, use it to inform your response. Quantitative Sampling Strategy: Be specific. Quantitative Data Collection Method: Be specific. Note: Use proper APA format. If helpful, support your postings and responses with specific references to the Learning‌‍‍‍‌‍‍‌‌‍‍‍‌‍‍‍‍‌‍‍ Resources.
