Alternative to Difference Scores: Polynomial Regression and Response with Professor Jeffrey Edwards **registration open**

Date: 11 March 2019 to 12 March 2019
Location: Alliance Manchester Business School

For decades, difference scores have been used in studies of congruence in organizational research. Despite their widespread use, difference scores have numerous methodological problems. These problems can be overcome by using polynomial regression and response surface methodology, which can examine a wide range of congruence hypotheses. This workshop will review problems with difference scores, introduce polynomial regression and response surface methodology, and illustrate the application of these methods using empirical examples.  Participants will be provided with data to analyze during the class with the goal of creating a hands-on experience that will clarify and reinforce the methods discussed. The workshop is aimed at doctoral students and early career researchers with a working knowledge of multiple regression analysis and its application in empirical research.
