Describe validity and reliability measures for qualitative research and how they compare to quantitative research constructs. First, we will define each of the terms and better understand their context. As Weiner [Jon07] describes in his analysis, validity is the degree to which any measurement approach or instrument succeeds in describing or quantifying what it is designed to measure. It is the extent to which the scores from a measure represent the variable they are intended to. On the contrary, reliability relates to the degree of which a measurement technique can be depended upon to secure consistent results upon repeated application. Reliability relates to consistency. Psychologists consider three types of consistency: over time (test-retest reliability), across items (internal consistency), and across different researchers (inter-rater reliability). [Pau15]. For quantitative researchers, reliability is a method used to established trustworthiness. Quantitative researchers use reliability by examining the consistency of a group of measurements or measuring instruments used in a study (also known as internal consistency). Researchers also use the test-retest method (also known as stability) to prove reliability by administering one measure to one group of individuals, wait for a certain amount of time and then re-administer the same instrument to the same group. In contrast to qualitative researchers’ credibility methods, quantitative researchers use internal validity methods to establish trustworthiness. Quantitative

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
