Answer 2

A Likert scale is a type of psychometric response scale often used in questionnaires, and is the most widely used scale in survey research. When responding to a Likert questionnaire item, respondents specify their level of agreement to a statement. The scale is named after Rensis Likert, who published a report describing its use (Likert, 1932).

It's fine for a simple questionnaire, however, it was found (in 1990's) to be useless for scientific surveys. I was working at the V&A museum at the time when we re-wrote the audit forms, as we were finding the old Likert style forms resulted in everbybody ticking the middle box when in doubt.

thus we reduced the number of options down to four, so in the audit, the surveyer had to choose between good and bad, and did not have an easy opt out box..

Answer 3

Do you mean the Likert scaling approach? This is the 5 response scale in survey methodology - Very Good / Good / Neutral / Poor / Very Poor.
