Qualitative Research

Explanation:

There are two types of research: Qualitative Research and Quantitative Research.

The Qualitative research uses a descriptive style (non-numeric such as gender, color, religion, etc.) in its data collection, analysis and results. This is called the "qualitative approach."

On the contrary, the "quantitative research" employs measurable quantities such as size, length, weight, etc. The data are then reported through statistical analysis. This is called the "quantitative approach."
