Likertskálára

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

The most common format involves five response options: strongly disagree, disagree, neutral, agree, and strongly agree. Other variations may include three, four, six, or seven options, depending on the research context and desired level of detail. The responses are assigned numerical values, allowing for quantitative analysis. For example, "strongly disagree" might be assigned 1, "disagree" 2, "neutral" 3, "agree" 4, and "strongly agree" 5.

Researchers use Likert scales to gauge respondents' intensity of feeling on a particular issue. The data collected can be analyzed in various ways, including calculating means, medians, and frequencies. It is important to note that while Likert scales are often treated as interval data for analytical purposes, they are technically ordinal data, meaning the order of responses matters, but the distance between them may not be equal. This distinction can influence the choice of statistical tests employed. Likert scales are widely adopted due to their simplicity in design and ease of understanding for respondents.
