Abstract:
Some beginning students of statistics and econometrics have difficulty with traditional algebraic approaches to explaining regression and related techniques. For these students, a simple and intuitive diagrammatic introduction may prove a useful framework to support further study. This paper presents a series of diagrams designed for use in an introductory econometrics course as an intuitive aid when first introducing fundamental concepts of the field. These diagrams are easily employed in the classroom as an enhancement to traditional teaching methods. Pedagogical suggestions and a few applied examples drawing on the diagrammatic framework are motivated and discussed.
