Applied Research vs Fundamental Research Applied research is a type of research in which the central goal is to find a conclusion or a solution for some pressing practical problem such as problems related to social, business, marketing and even political-related problems. Fundamental research, also known as basic research, is a type of research in which its central goal is just to find information to add to an already existing organized body of scientific knowledge for generalization or theory formulation. This is basically a research done to gather knowledge for knowledge’s sake. An example for this type of research would be a study related to natural phenomena or human behavior. b. Qualitative vs Quantitative Research Quantitative research, as its name implies, is based the collection and analysis of numerical data. Numerical, or quantitative, data are types of data which can be quantified, counted, and measured. Qualitative research uses numbers, statistics, and graphs to report the data and to show quantitatively the result of the study. Examples of methods used for quantitative research is close-ended question surveys and life science experiment. Meanwhile, qualitative research focuses on the qualitative phenomenon, exploring ideas, and formulating theories. One of the main purposes of this research is to investigate and discover underlying and motives of human behavior. Unlike quantitative research, qualitative research is descriptive, which means it uses words rather than numbers to present the result of the study. Some methods used for this research is an open-ended question survey and interviews. c. Conceptual Research vs Empirical Research Conceptual research is usually done by philosophers and thinkers to study abstract ideas, concepts, or theories to reinterpret them and make connections to previous and current phenomena. This does not involve any practical experiments. Empirical research, on the other hand, is a data-based research. Also known as experimental research, empirical research has dependent and independent variables in which their relationship is investigated to prove or disapprove the hypotheses. 2. Briefly discuss the types of quantitative approach a. Inferential Approach Inferential approach is done to make an inference or a conclusion for the study. The experiment or method usually is done on small sample population and the data are used as the basis for the conclusion on a larger scope. b. Experimental Approach Experimental approach is used to determine the relationship of the variables. The independent variables are controlled and manipulated to see its effects on the dependent variables. c. Simulation Approach Simulation approach is done to demonstrate the study by using an artificial environment through simulation software. By using this approach, researchers can visualize the effects of the parameters involved to his project
