Likertskálával

Likertskálával is a psychometric scale commonly used in questionnaires and surveys to measure attitudes, opinions, and perceptions. It is named after its creator, psychologist Rensis Likert, who developed it in 1932. The scale typically consists of a series of statements, and respondents are asked to indicate their level of agreement or disagreement with each statement using a predefined set of response options.

The most common Likert scale uses five response options: strongly disagree, disagree, neutral, agree, and strongly agree. However, variations with four, six, or seven options also exist. The neutral option allows respondents to express indifference or lack of opinion, while an even number of options forces a choice, eliminating neutrality.

Data collected using Likert scales can be treated as ordinal or interval data, depending on the analytical approach. Ordinal data implies a ranked order of responses, while interval data assumes equal distances between scale points, allowing for more advanced statistical analyses like calculating means and standard deviations.

Likert scales are widely employed in various fields, including social sciences, market research, and education. They offer a straightforward and quantifiable method for gathering subjective data, making them a valuable tool for researchers seeking to understand respondent sentiment and preferences. The simplicity of response options contributes to high response rates and ease of data interpretation.
