How Regression Analysis Works

Regression analysis is a statistical method used to establish relationships between a dependent variable (outcome) and one or more independent variables (predictors). The goal is to create a mathematical model that can predict the value of the dependent variable based on the values of the independent variables. For instance, a researcher might use regression analysis to examine the relationship between a person's income and their education level, job experience, and geographic location. The resulting model can be used to predict a person's income based on their demographic characteristics.
