Likerttyyppistä

Likerttyyppistä refers to a type of psychometric scale commonly used in questionnaires and surveys. It is named after psychologist Rensis Likert, who developed the scale in 1932. The core principle of a Likert scale is to measure attitudes, opinions, or beliefs by presenting respondents with a series of statements. For each statement, individuals are asked to indicate their level of agreement or disagreement from a range of predefined options.

These options typically represent a spectrum of intensity. Common response categories include "Strongly Disagree," "Disagree," "Neutral," "Agree," and "Strongly Agree." Sometimes, more nuanced options or a numerical scale (e.g., 1 to 5) are employed. The scale allows for the quantification of subjective responses, enabling researchers to analyze patterns, trends, and differences in attitudes among groups.

When constructing Likert-type items, it is crucial that the statements are clear, concise, and unambiguous. The response options should also be mutually exclusive and exhaustive. Data collected from Likert scales can be analyzed using various statistical methods, including calculating means, medians, and frequencies. It is widely used in fields such as psychology, sociology, marketing research, and education to gather data on a variety of subjects. The ease of administration and interpretation makes it a popular tool for survey design.
