Quantitative Analysis is a method used to evaluate data through mathematical and statistical techniques. It focuses on quantifying relationships, patterns, and trends within numerical data, allowing analysts to make informed decisions based on measurable evidence. This approach is commonly applied in fields such as finance, economics, and social sciences, where data-driven insights are crucial. Analysts often use tools like statistical software and mathematical models to interpret large datasets. By employing techniques such as regression analysis and hypothesis testing, they can identify correlations and predict future outcomes. Ultimately, quantitative analysis helps organizations optimize strategies and improve performance based on solid data.
