quantitative: Related to, or expressed in terms of measured numeric values, quantity or statistical comparison derived from systematic survey, observation or analysis of the subject; this may include probabilistic evaluation. Quantitative research is based on measurable data gathered from a wide range of sources, often followed by objective analysis. A general description includes facts, figures and scientific observation that can be statistically analyzed and then can be reduced to something that can be enumerated. The collected data is often subjected to statistical tests to see if the results are internally consistent or representative of random chance. Typically, it describes patterns and trends in size and quantity. Quantitative data is often classified as being real.
