Quantitative analysis is a method used to evaluate data through mathematical and statistical techniques. It focuses on quantifying relationships, behaviors, and trends by using numerical data. This approach is commonly applied in fields like finance, economics, and social sciences to make informed decisions based on measurable evidence. Analysts often use tools such as statistical software and mathematical models to interpret data sets. By analyzing patterns and correlations, quantitative analysis helps in forecasting future outcomes and assessing risks. This objective approach allows researchers and decision-makers to draw conclusions based on solid data rather than subjective opinions.
