Likert Scale: A Guide to Understanding and Using This Psychometric Tool

The Likert scale, named after psychologist Rensis Likert, is a popular psychometric tool used to measure attitudes, opinions, and perceptions. This scale presents a series of statements or items related to a particular construct. Respondents are then asked to express their level of agreement or disagreement with each statement using a predetermined scale, typically ranging from 1 to 5 (e.g., 1-strongly disagree to 5-strongly agree).

The Likert scale's strength lies in its ability to quantify subjective responses, providing valuable insights into individuals' attitudes, perceptions, and preferences. This makes it particularly useful in research, surveys, and the social sciences for assessing and analyzing people's opinions and behaviors.
