These are considered under qualitative and quantitative data as under: Qualitative data: Nominal scale: In this scale, categories are nominated names (hence "nominal"). Nominal scale is often used in research surveys and questionnaires where only variable labels hold significance. In addition, numerical data can be further subdivided into interval and ratio data.
