Level of measurement or scale of measure is a classification that describes the nature of information within the values assigned to variables. [1] Psychologist Stanley Smith Stevens developed the best-known classification with four levels, or scales, of measurement: nominal, ordinal, interval, and ratio.
Research by Labovitz [22] and Traylor [23] provide evidence that, even with rather large distortions of perceived distances between scale points, Likert-type items perform closely to scales that are perceived as equal intervals. So these items and other equal-appearing scales in questionnaires are robust to violations of the equal distance ...
Scaling of data: One of the properties of the tests is the scale of the data, which can be interval-based, ordinal or nominal. [3] Nominal scale is also known as categorical. [6] Interval scale is also known as numerical. [6] When categorical data has only two possibilities, it is called binary or dichotomous. [1]
Interval scales are used. Relative assessments are more important than absolute assessments. Responses are often graphically implemented (n order to avert biases associated with some numbers) and are subsequently transformed to numerical assessments, such as on a scale of 0 - 60 or 0 - 100.
Thus, survey researchers must be conscious of their wording when writing survey questions. [26] It is important for researchers to keep in mind that different individuals, cultures, and subcultures can interpret certain words and phrases differently from one another. [26] There are two different types of questions that survey researchers use ...
Phrase completion scales are a type of psychometric scale used in questionnaires. Developed in response to the problems associated with Likert scales , phrase completions are concise, unidimensional measures that tap ordinal level data in a manner that approximates interval level data.

Survey methodology is "the study of survey methods". [1] As a field of applied statistics concentrating on human-research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys.
