Reliability and Validity
This discussion has two options, depending on whether you are proposing a quantitative or qualitative methodology for your course project.

(My research is Qualitative)

Option 2 – Qualitative
Reintroduce your study to your peers with the working title, research question, and statement of purpose. Then, evaluate threats to your study's validity and reliability. Discuss the following:
•    Describe the types of data that will be collected, including your interview questions and how the data will be collected.
•    Discuss how you will establish dependability (reliability) of the data.
•    Discuss how you will establish the credibility (validity) of the data (using your research textbooks and the information from the qualitative validity article assigned in this unit's studies, "Examining the Validity Structure of Qualitative Research."
•    Discuss how the credibility and dependability of the research contribute to the scientific merit of the research.
Your post should have 250–300 words and include scholarly references and citations.

(You must use at least two references to support your work) Let me know if you have any questions or need additional information to complete this assignment) 

Unit reading: 

Validity and Reliability
In quantitative research, we refer to the concepts of validity and reliability to tell us how well the study measured what it was supposed to measure and how much we trust the accuracy of the results. We address these same basic issues in qualitative research, but they are referred to as credibility and dependability, respectively.

Validity as a Unifying Concept
The process of reviewing literature and interpreting research in light of other published research studies revolves around the concept of validity in research design. What is validity? There is not a unified consensus regarding the definition of validity in research design (Pedhazur & Schmelkin, 1991). However, at its core, validity in quantitative research involves confirmed truth, or how accurately an instrument or study manifests what it is purported to examine (Edmonds and Kennedy, 2017).

Reliability in Qualitative Research
Just as credibility and transferability roughly correlate to the concepts of internal and external validity in quantitative research, reliability has its counterparts in qualitative research as well. We refer to these issues as confirmability and dependability. Reliability, with its emphasis on replication, does not apply well to qualitative human services research studies since each is unique—something that is intrinsic in the process. 

In this unit, you will evaluate the credibility and dependability within a selected qualitative research article from your Review of the literature. And likewise, you will analyze and evaluate the properties of reliability and validity within a quantitative investigation you have identified in your Review of Literature within your topic of interest. You will be asked to continue to develop your literature review.
