Five-Point Likert Scale

A Five-Point Likert Scale is a Likert Psychometric Scale that is based on a 5-point rating scale.

• Example(s):
  • a five-point Likert similarity scale used in the SemEval-2017 Task 2:

4	Very similar	The two words are synonyms (e.g., midday-noon or motherboard-mainboard).
3	Similar	The two words share many of the important ideas of their meaning but include slightly different details. They refer to similar but not identical concepts (e.g., lion-zebra or firefighter-policeman).
2	Slightly similar	The two words do not have a very similar meaning, but share a common topic/domain/function and ideasor concepts that are related (e.g., house-window or airplane-pilot).
1	Dissimilar	The two words describe clearly dissimilar concepts, but may share some small details, a far relationship or a domain in common and might be likely to be found together in a longer document on the same topic (e.g., software-keyboard or driver-suspension).
0	Totally dissimilar and unrelated	The two words do not mean the same thing and are not on the same topic (e.g., 'pencil-frog or PlayStation-monarchy).

  • A Likert scale is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale) is often used interchangeably with rating scale, although there are other types of rating scales. The scale is named after its inventor, psychologist Rensis Likert. Likert distinguished between a scale proper, which emerges from collective responses to a set of items (usually eight or more), and the format in which responses are scored along a range. Technically speaking, a Likert scale refers only to the former. The difference between these two concepts has to do with the distinction Likert made between the underlying phenomenon being investigated and the means of capturing variation that points to the underlying phenomenon. When responding to a Likert item, respondents specify their level of agreement or disagreement on a symmetric agree-disagree scale for a series of statements. Thus, the range captures the intensity of their feelings for a given item. As such, Likert scales have found application in psychology and social sciences, statistics, business and marketing. A scale can be created as the simple sum or average of questionnaire responses over the set of individual items (questions). In so doing, Likert scaling assumes distances between each choice (answer option) are equal. Many researchers employ a set of such items that are highly correlated (that show high internal consistency) but also that together will capture the full domain under study (which requires less-than perfect correlations). Others hold to a standard by which "All items are assumed to be replications of each other or in other words items are considered to be parallel instruments". By contrast, modern test theory treats the difficulty of each item (the ICCs) as information to be incorporated in scaling items.

  • QUOTE: Various kinds of rating scales have been developed to measure attitudes directly (i.e. the person knows their attitude is being studied). The most widely used is the Likert scale (1932).

    In its final form, the Likert scale is a five (or seven) point scale which is used to allow the individual to express how much they agree or disagree with a particular statement.
