Reliability and Validity
Validity is the degree to which data is accurate. Reliability is a measure of how the results can be repeated (Northouse, 2019). For instance, if I am measuring my height and using a measuring tape made by a reputable company, and it is held against the ground without buckling, one could assume the result is valid. However, if multiple people hold the measuring tape differently and the results vary, the result would not be reliable.
Instruments Utilized
After considering validity and reliability, a method of obtaining information is needed. That we call an instrument. The instrument used by Chaudhary et al. (2013) was a human resource development (HRD) survey of 38 questions with a 5-point scale to indicate the participants’ responses. The survey dealt with HRD as a measure of at least three dimensions of HRD. HRD includes a general climate, a culture of openness, confrontation, trust, autonomy, proactivity, authenticity, and collaboration.
Concepts of Instrument’s Measurements and Psychometric Properties
The HRD scale included answers ranging from almost always true to not at all true and came with a point scale to indicate the frequency of each response. The tool was intended to include a 38-factor report of reliability and why each chosen factor was used. Chaudhary et al. stressed the importance of reducing the number of HRD climate dimensions to make the study easier to comprehend.
Use of Instrument in Doctoral Study
The HRD climate survey instrument could be used as-is or modified for any survey because it uses a point system to analyze a rating scale. While a qualitative study may use rankings to indicate why participants feel the way they do, quantitative research would use the point system to generate statistics showing the frequency of responses. Kelley-Quon (2018) stated that surveys could merge qualitative and quantitative research methods using something like a 5-item Likert scale.
