Qualitative data and quantitative data refer to different kinds of data and originate from statistics. Both of these types of data can be subjective or objective. Neither is exclusive to the other.
Subjectivity is used to refer to the condition of being a subject; the quality of a subject’s perspective, experiences, feelings, beliefs, and desires. Subjective information is one person’s opinion.
Objectivity is the idea that scientists, in attempting to uncover truths about the natural world, must aspire to eliminate personal biases, a priori commitments, emotional involvement, etc.

Qualitative data comes from the word quality. Indicates a description of something. It focuses on the subject’s properties, characteristics, features, etc.
