From the logical process of research, quantitative analysis is close to the research of hypothesis-deduction method, which not only retains the characteristics of attaching importance to observation experiments and collecting empirical data, but also attaches importance to deductive reasoning of logical thinking. The application of hypothesis combines observation experiment and mathematical deduction. Because of this, quantitative analysis often emphasizes the objectivity and observability of physical objects, the interrelationship and causality between phenomena and variables, and requires researchers to strive for objectivity and ethical neutrality in their research.
