to establish a linear equation that best predicts the dependent variable based on the independent variables. Relevance in Applied Statistics In applied statistics, linear regression serves as a fundamental tool for
dimensions) that explains the variation in the response variable based on the predictors. The basic form of a simple linear regression model is: \[ y = \beta_0 + \beta_1 x + \varepsilon \] Where: \( y \) is the dependent variable. \( x \)
