Original Question

Post an analysis of sources and methods of data collection in the context of your DBA doctoral research question. In your analysis, do the following:

· Explain how the “Four Principles of Data Collection” from Yin (2018) support your ability to address your DBA doctoral research question.

· Explain the importance of utilizing multiple sources of evidence and triangulation within the data collection process. Be sure to address the specific types of data triangulation (data, investigation, investigator, methodological) and their relationship to data quality. Be sure to provide a scholarly example to support your explanation.

Be sure to support your work with a minimum of two specific citations from this week’s Learning Resources and one or more additional scholarly sources.

Four Principles of Data Collection

Both reliability and validity make the qualitative study rigorous, and the subjective nature of unstructured data collection poses a threat to validity (Morse, 2015). Yin (2018) identified four principles of data collection to ensure high-quality case studies: use multiple sources of evidence, a case study database, maintain a chain of evidence, and exercise care using electronic sources of evidence. For my qualitative study, I was considering data collection using interviews only, and I realize I must include one other source. Including another source will require a case study database for orderly compilation of all the data. A database will also enable to maintain a chain of evidence and ensure no evidence is lost and all findings can be traced back to the collected evidence.

Utilizing Multiple Sources of Evidence and Triangulation

Multiple sources of evidence assist in establishing quality and likely to be more convincing and accurate (Yin, 2018). Yin (2018) identified four types of triangulation-the triangulation of data sources, investigator or evaluators, theory or perspectives to the same dataset, and methods. By identifying similar, converged findings from data collected from multiple sources, data triangulation helps with construct validity of the study (Yin, 2018). Qualitative data collected using interviews can be objective which is reproducible, numbered, quantified or measured (Anyan, 2013). DBA doctoral study handbook (Walden University, n.d.) requires a minimum of two data collection methods. Therefore, I am considering using surveys in addition to interviews and potentially consider data triangulation to develop converged findings.

Yin (2018) speaks to using multiple sources of evidence for a case study because it has higher quality.  While examing Yin’s “Four Principle of Data Collection” it would be ideal to incorporate and consider each principle in your case study.  Although the information could be overwhelming, I believe it affords the researcher to use what is useful to the study and determine what is not as useful.   Additionally, researcher could find the less useful data as an avenue to generate more conversation.  Yin (2018), suggest that there is little excuse for omitting a thorough review of documentary evidence.  He also indicates that if you follow four principles of data collection because it helps deal with the problems of establishing the construct validity and reliability of the evidence.

There are multiple approaches to satisfying a case study.  The strategy I plan to implement is a mixed method research approach.  This form of triangulation will allow me to take a deeper dive into my study.  Human behavior will determine my newfound concepts because each response is based on the human experience (Turner, Cardinal, & Burton, n.d.).  . Yin (2018)  suggest that using multiple sources of evidence permits going beyond appreciating the breadth of a case study’s scope.   The author implies that you also will have an opportunity to pursue a critical methodological practice—to develop converging lines of inquiry. According to (Anyan, 2013) the interviewee may view the interviewing situation from several perspectives to reflect on his or her own dynamisms within the circumstance of the interview.

**Dr. Faint & Class – my cousin was admitted into the hospital this morning – she was having major chest pains.  She is a Walden student and when I went to visit her this evening she was up posting her assignments. SMH!  Thankfully she is feeling better and hopefully they will release her soon.  Please say a prayer for her speedy recovery.**
