Quantitative versus qualitative data/analysis

Qualitative analysis is the scientific study of data that can be observed but cannot be measured. It focuses on cataloging the qualities of data. Examples of qualitative data can be:

  • The softness of your skin
  • How elegantly someone runs

Quantitative analysis is the study of actual values within data, with real measurements of items presented as data. Normally, these are values such as:

  • Quantity
  • Price
  • Height

pandas deals primarily with quantitative data, providing you with extensive tools for representing observations of variables. Pandas does not provide for qualitative analysis, but does let you represent qualitative information.
