Likertskaalaid

Likertskaalaid, often referred to as a Likert scale, is a psychometric scaling method widely used in questionnaires and surveys to measure attitudes, opinions, and behaviors. It was developed by psychologist Rensis Likert in 1932. The scale typically presents a statement or question, followed by a range of response options that reflect varying degrees of agreement or disagreement.

Common response options include a five-point scale such as "Strongly Disagree," "Disagree," "Neutral," "Agree," and "Strongly Agree." Other variations exist, such as a seven-point scale or scales that use numerical values. The strength of the Likert scale lies in its simplicity and ease of administration and interpretation.

When analyzing data collected using Likert scales, individual item responses are often summed or averaged to create a composite score for a particular construct or attitude. This allows researchers to compare groups or track changes over time. It is important to note that while Likert scales are ordinal, meaning the categories have a natural order, treating them as interval data for certain statistical analyses is a common practice, though it is sometimes debated. The primary goal is to gain insights into respondents' subjective experiences and perceptions.
