Quantitative analysis refers to a statistical method used in research and data analysis that involves measuring or quantifying variables, often using mathematical techniques. It is concerned with the collection, analysis, interpretation, presentation, and organization of numerical data, which can be used to make informed decisions based on empirical evidence. This type of analysis helps to identify patterns, trends, relationships, and associations between different variables within a dataset, providing valuable insights into complex issues or problems. It is commonly used in various fields such as economics, finance, marketing, healthcare, and social sciences, among others, to help make data-driven decisions based on empirical evidence rather than subjective opinions or beliefs.
