Mod 4 Discussion Question: Theory and Research: Sampling, Reliability, Validity, and Trustworthiness

/0 Comments/in /by

This module continues with an emphasis on the planning phase of research, focuses on sampling, reliability, and validity in quantitative research. Topics covered include probability and non-probability sampling, measurement, consistency and content validity. Also, this module focuses on trustworthiness of qualitative research. Topics covered include credibility, transferability, dependability, and confirmability as criteria for trustworthiness.

Sampling involves decisions about who or what will be tested, observed, or interviewed in your study. A sampling frame is the set of people (subjects) you will draw your sample from. A sampling design describes the process used to choose subjects for the sample. In quantitative research, the goal is to achieve randomness and avoid any systematic procedure that might introduce bias.

It is important to achieve the highest quality of measurement possible in your research. Reliability and validity are the two primary aspects of the quality of quantitative research measures. This chapter addresses issues of reliability in quantitative studies. Evaluation of the reliability of research measures is concerned with questions of consistency. Validity is the extent to which the measure you use is true to its intended purpose.

Quality is as essential to qualitative research as it is to quantitative research. The term often used to describe the desirable characteristics of both the process and the product of qualitative research is rigor, which refers to adherence to high standards in the conduct of research. Attributes of rigorous qualitative research include credibility, transferability, dependability, and confirmability.

Discussion Question:

What are some issues to consider when using face validity? What are some potential pitfalls to avoid, and how would you avoid hem? Give a couple examples.

Your initial posting should be 250 to 350 words in length and utilize at least one scholarly source other than the textbook.

Assignment Description:

Based on what you have learned so far this week, create a PowerPoint presentation with detailed notes for each slide that addresses each of the following points/questions.

No audio recording is required. Be sure to completely answer all the questions. Use clear headings that allow your professor to know which bullet you are addressing on the slides in your presentation. Support your content with at least four (4) citations throughout your presentation. Make sure to reference the citations using the APA writing style for the presentation. Include a slide for your references at the end.

Follow best practices for PowerPoint presentations by going to the Writing and Resource center, Module 3: Assignments, Microsoft, and utilize the Microsoft Overview and the Creating a Quality PowerPoint video.

Visit the Center for Disease Control Emerging Infectious Disease website. Choose one journal, article, or case study and explain the type of research design that was used in this study.

Summarize your source and include an explanation of the following questions in your response:

• Is it evident that primary, secondary, or meta-analysis was used?• What role did surveys play, if any? Explain.• Were there any flaws or discrepancies in the data? Why or why not?

Locate two journal articles, one that uses descriptive epidemiology, and the other that uses analytic epidemiology.

• Summarize each article and compare and contrast the research designs (2 slides).

Review this site: https://www.hhs.gov/ohrp/education-and-outreach/about-research-participation/protecting-research-volunteers/index.html then write a summary of recommendations on Protecting Research Participants (2-3 slides).

 

The following specifications are required for this assignment:

  • Length: 15-17 slides; answers must thoroughly address the questions in a clear, concise manner
  • Structure:
  • Title: 1 slide
  • Articles chosen: at least 1 slide
