Likertskálán

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

The most common format of a Likert scale involves five response options, such as "Strongly Disagree," "Disagree," "Neutral," "Agree," and "Strongly Agree." Other variations may include three, four, six, or seven points, depending on the research objective. The response options are usually presented in a symmetrical manner around a neutral midpoint, allowing for the measurement of both positive and negative sentiments.

Data collected from Likert scales can be analyzed in various ways. Individual items can be treated as ordinal data, or they can be summed or averaged to create a composite score for a particular construct. This allows researchers to calculate means, medians, and frequencies to understand the overall distribution of responses and identify trends. Likert scales are widely applied in fields such as psychology, sociology, marketing research, and education due to their simplicity and effectiveness in quantifying subjective information.
