Finding Qualitative or Quantitative Research

 

Qualitative and quantitative are terms to describe the type of information used in research.

 

Qualitative: "relating to the quality of an experience or situation rather than to facts that can be measured" [1]
Quantitative: "related to an amount that can be measured" [2]

 

Some research can be categorized as one or the other, but others used a mix of both approaches.
