The goal of this article is to provide readers who do not have extensive statistics background with the basics needed to understand these concepts.ĭeveloped in 1932 by Rensis Likert 1 to measure attitudes, the typical Likert scale is a 5- or 7-point ordinal scale used by respondents to rate the degree to which they agree or disagree with a statement ( table). Thus, understanding the interpretation and analysis of data derived from Likert scales is imperative for those working in medical education and education research. A sizable percentage of the educational research manuscripts submitted to the Journal of Graduate Medical Education employ a Likert scale for part or all of the outcome assessments. Common uses include end-of-rotation trainee feedback, faculty evaluations of trainees, and assessment of performance after an educational intervention. Likert-type scales are frequently used in medical education and medical education research.
