CHAPTER 1 NATURE OF INQUIRY AND RESEARCH PREPARED BY: CESARIO C. SANCHEZ, JR., LPT  What is Quantitative Research? Quantitative research, according to Aliaga and Gunderson (2000), is "explaining phenomena by collecting numerical data that are analyzed using mathematically based methods (in particular statistics)." This type of research utilizes numbers and statistical analysis.  Phenomenon is a peculiar incident that can happen anywhere, with any discipline or in any organization. Examples are increase in sales, change in turn-over rates, change in drop-out rates, decrease in the number of failing students in Mathematics, shift in the percentage of dengue patients, rise in the rate of drug addiction among the youth, and decrease in juvenile crime rates in the rural areas.  Quantitative Research is Traditional Positivist scientific method Follow a set of orderly and disciplined procedures to acquire information It utilizes deductive reasoning It generate predictions that are tested in the real world.  Quantitative Research is It generate predictions that are tested in the real world.
