The reliability of the fuzzy scale for assessing the responses of a person in an opinion questionnaire (which is usually treated as a Likert-type questionnaire) is analyzed. Thus, a comparison between a classical Likert scale-based questionnaire and its fuzzy rating scale-based version in terms of their reliability is established. For this purpose, some questions of the Grasha-Riechmann student...

We applied both types of methods to the analysis of actual Likert data ...

This study investigates how factors such as personality, gender, procrastination, boredom and ones values may affect the amount of time they spend on Facebook, further concluding that they are either overly obsessive o...
