The rank scale is often used in research to discover and measure respondents' preferences – primarily in the marketing industry. This is a type of ordinal scale, the use of which consists in ordering the categories in the survey by a respondent according to a specific criterion. The questionnaire then contains answers scaled according to the nominal scale, which under the influence of information provided by the respondent turns into a scale of rank.
The main advantages of the rank scale include, on the one hand, the ease of its creation, and on the other, understandability for the respondent – without the need to attach complicated instructions or formulas to the study.
