Having viewed some of the highly edited videotaped material of Terri Schiavo and having seen other patients in a persistent vegetative state, I am not surprised that family members and others unfamiliar with this condition would interpret some of her apparent alertness and movement as meaningful.
A Likert Scale is a type of psychometric scale frequently used in psychology questionnaires. It was developed by and named after organizational psychologist Rensis Likert. Self-report inventories are one of the most widely used tools in psychological research.
It is a good discussion. In my opinion, the Likert scale is an ordinal scale, because with this scale we can't measure the distance of two levels of scale. In fact, we can measure the numerical distance of 4 from 5. But, this difference don't have sense in the qualitative argument of the respondents.
