Quantitative Research
Quantitative research (pronunciation: kwon-tuh-tey-tiv ree-surch) is a systematic empirical investigation of observable phenomena via statistical, mathematical, or computational techniques. The objective of quantitative research is to develop and employ mathematical models, theories, and hypotheses pertaining to phenomena.
Etymology
The term 'quantitative research' is derived from the Latin word 'quantus' meaning 'how much' and the English word 'research' meaning 'systematic investigation'.

Definition
Quantitative research is a type of research methodology that involves a detailed empirical investigation of a particular subject matter using statistical, mathematical, and computational techniques. It is primarily used in fields such as psychology, sociology, marketing, economics, and political science, among others. The main aim of quantitative research is to quantify the data and generalize the results from the sample to the population of interest.
Methodology
Quantitative research methodology involves the collection and analysis of data. The data collected is numerical or can be converted into numbers. This data is then analyzed using statistical and mathematical methods. The results of this analysis are then used to draw conclusions about the larger population.
Advantages and Disadvantages
Quantitative research has several advantages. It allows for a broader study, involving a larger number of subjects, and enhancing the generalization of the results. It also allows for greater objectivity and accuracy of results. However, it also has its disadvantages. It can be expensive and time-consuming, and it may not be as flexible or open to contextual and interpretive understanding as qualitative research.
