What is an example of a qualitative property?
Qualitative properties are properties that are observed and can generally not be measured with a numerical result. They are contrasted to quantitative properties which have numerical characteristics.
Qualitative and Quantitative Data. Quatitative data are anything that can be expressed as a number, orquantified. Examples of quantitative data are scores on achievement tests,number of hours of study, or weight of a subject.
- Qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. They do not involve measurements or numbers. For instance, colors, shapes, and textures of objects are all qualitative observations.
- Ordinal data is a categorical, statistical data type where the variables have natural, ordered categories and the distances between the categories is not known. These data exist on an ordinal scale, one of four levels of measurement described by S. S. Stevens in 1946.
- Qualitative Research. Qualitative Research is primarily exploratory research. It is used to gain an understanding of underlying reasons, opinions, and motivations. Qualitative data collection methods vary using unstructured or semi-structured techniques.
Data that approximates or characterizes but does not measure the attributes, characteristics, properties, etc., of a thing or phenomenon. Qualitative data describes whereas quantitative data defines.
- There are a variety of methods of data collection in qualitative research, including observations, textual or visual analysis (eg from books or videos) and interviews (individual or group). However, the most common methods used, particularly in healthcare research, are interviews and focus groups.
- Each is broken down into two sub-types: qualitative data can be ordinal or nominal, and numeric data can be discrete (often, integer) or continuous. Because qualitative data always have a limited number of alternative values, such variables are also described as discrete.
- Quantitative: Numerical or statistical information (data), which often comes from surveys, surveillance or from administration records. Qualitative:Descriptive information, which often comes from interviews, focus groups or artistic depictions such as photographs.
