Quantitative analysis is a method used to evaluate data through mathematical and statistical techniques. It focuses on quantifying relationships, behaviors, and patterns to make informed decisions. This approach is commonly applied in fields like finance, economics, and social sciences, where numerical data is essential for analysis. In quantitative analysis, researchers often use tools such as statistical models, regression analysis, and data visualization to interpret results. By converting qualitative information into numerical values, analysts can identify trends, forecast outcomes, and assess risks, ultimately aiding in strategic planning and problem-solving.
