A trenchant and passionate dispute over the use of parametric versus non-parametric methods for the analysis of Likert scale ordinal data has raged for the past eight decades. The answer is not a simple "yes" or "no" but is related to hypotheses, objectives, risks, and paradigms. In this paper, we took a pragmatic approach. We applied both types of methods to the analysis of actual Likert data ...

Cronbach’s Alpha coefficient is the most popular method of examining reliability. It is typically used when the researcher has several Likert-type items that are summed or averaged to make a composite score. Distribution of alpha coefficient has been subjected of many studies. In this study relationship between randomness and Cronbach alpha coefficient were investigated and in this context, pre...

BACKGROUND To clarify the relationship between the probability of prostate cancer scaled using a 5-point Likert system and the biological characteristics of corresponding tumor foci. METHODS The present study involved 44 patients undergoing 3.0-Tesla multiparametric MRI before laparoscopic radical prostatectomy. Tracing based on pathological and MRI findings was performed. The relationship be...

There is many software development methodologies exist that is used to control the process of developing a software system. No exact system was found which could help the software engineers for selection of best software development methodology. This paper present the framework of expert system combined with Likert scale. With the help of Likert scale we create a rule based model and assign som...

Objectives: There is an increasing need for a larger and better trained workforce in medical informatics. The goal of the American Medical Informatics Association 10×10 program is to educate 10,000 clinicians in medical informatics by the year 2010. Methods: We adapted an on-line introductory graduate course toward this goal. It was evaluated using Likert-scale and open-ended questions. Results...
