Correlation analysis is a statistical technique that is used to measure and quantify the relationship between two or more variables. It helps researchers understand the degree to which changes in one variable are associated with changes in another variable. Correlation analysis can be used to determine the strength and direction of a relationship between variables, and it is often used in descriptive and inferential statistics to identify patterns and trends in data. This analysis can provide valuable insights into the connections between different factors and can help researchers make informed decisions based on the relationships between variables.
