Quantitative vs Qualitative. Quantitative and Qualitative are two terms between which a variety of differences can be identified. Quantitative has a lot to do with the quantity of an object or a person. On the other hand, qualitative has a lot to do with the quality or the attribute of an object or a person.
Qualitative is typically based on smaller sample sizes and inferences are made from observations and non structured techniques.
