Discussion: Reliability and Validity in Measurement

So far in this course, you have used existing data sets for weekly analyses; however, when writing your quantitative proposal, you will need to collect data using a preestablished instrument, one with sound psychometric (reliability and validity) properties, and an instrument that measures the variables/constructs you propose to measure. For this Discussion, you will explore the concepts of reliability and validity within a peer-reviewed journal article.

To prepare for this Discussion, select one of the following two required articles from this week’s Resources: Chaudhary et al. (2013) or Tang (2013). Assume you are contemplating using the instrument identified in your chosen article to measure the purported construct(s) in your study.

By Day 3

Post an explanation of the importance of psychometrically (reliability and validity) sound instruments to measure constructs within quantitative business research. In your explanation, do the following:

  • Describe the similarities and differences of reliability and validity within the context of quantitative business research.
  • Identify the instrument utilized in your chosen article, including relevant details such as requirements or tools.
  • Discuss the concepts of the instrument’s measurements and their psychometric properties.
  • Explain why or why not you would use this instrument in your own DBA Doctoral Study, providing support based upon your assessment of its psychometric properties.

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

Refer to the Week 6 Discussion Rubric for specific grading elements and criteria. Your Instructor will use this rubric to assess your work.
