Regression in statistics is a powerful analytical method used to examine the relationship between variables and predict outcomes. It helps researchers understand how a dependent variable changes when one or more independent variables are modified. Common types include linear regression and multiple regression, both widely used in data analysis, economics, business forecasting, and scientific research. By identifying trends and patterns, regression analysis supports decision-making and reveals hidden insights in data. Learning the definition of regression in statistics is essential for students, analysts, and professionals who want to interpret data accurately and make reliable predictions based on numerical evidence.
