The primary objective of regression analysis is to examine relationships between variables. This statistical method allows researchers to determine how changes in one or more independent variables affect a dependent variable. By analyzing these relationships, regression provides insights into the nature and strength of the connections between variables, which can be particularly useful in predictive modeling and hypothesis testing.

In practical applications, regression analysis can help identify trends, make forecasts, and understand the dynamics of various factors influencing an outcome. It is particularly valuable in fields such as economics, finance, and social sciences, where understanding the interplay between factors is crucial for informed decision-making. This means the focus on relationships distinguishes regression analysis from other statistical methods, emphasizing its unique role in data analysis.
