A qualitative datum is one that is expressed as some quality/property of a particular entity, rather than a numerical value.
Conversely, a quantitative datum is one that is expressed as a quantity (or number), as opposed to a quality of a particular entity.
Hence, qualitative and quantitative data are essentially opposite data types.

Imagine you found a whale with many cuts. Qualitive data would be a description of the whale's general health. Quantitive data would be counting how many cuts the whale has, measuring how deep and long the wounds are. Quantitative = measurement or count
Qualitative = an impression, a description, a comparison (no numbers)
Quantitative Data involves Numbers. Quantitative data also refers to research which involves a high number of respondents or data points, whereas qualitative data has fewer respondents or data points.
Qualitative Data involves characteristics that cannot be easily measured or counted. Qualitative data also involves language more than numbers.
If you mean qualitative and quantitative data, then data would be dealing with numbers to describe a statistical analysis whereas qualitative represents things that cannot be expressed as numbers such as color.
Qualitative and quantitative data are both 2 important types of data. Qualitative data is data based on observation and description. An easy way to remember this, Qualitative ---> QUALity. Examples of qualitative data are when you record colors, smells, textures, etc... Quantitative data is based on numerical values. An easy way to remember this, Quantitative ---> QUANTity. An example of quantitative data are any type of numerical values.
Quantitative observations are the data collected in an experiment, mostly numbers. Qualitative observations would usually include written answers to analysis questions.
Qualitative data is describing by looks (I.e. The plant is green, or the person is taller than the dog) Quantitative data is describing by numbers (I.e. 8' tall, or 35 inches long)
Quantitative data deals with numbers and data that are measurable. Qualitative data, meanwhile, deals with descriptions and data that are observable but not measurable.
