Linear and quadratic regression: Comparative analysis of effect on organizational behavior measures

Abstract

This study presents comparative analysis of multiple linear regression model and quadratic regression. Organizational values (actual and desired) were used as independent variables and job satisfaction as the dependent variable. The sample consisted of 213 workers from all regions of Brazil, men and women, mostly with higher education, working in various industries. The quadratic regression resulted in variance explanations of greater magnitude when compared to the linear model. Surface analysis charts expanded the understanding of the effects promoted by the independent variables on the dependent. Considerations regarding the selection of regression models in the academic context and in organizational practice are provided.
