Research on the relation between handedness and mortality sometimes reveals that older left-handed individuals are underrepresented in the population (Coren & Halpern, 1991; Porac & Coren, 1981).

Specifically, students attempt to explain why handedness is related to mortality after viewing a graphical representation of this relation. While explaining the relation, students address many issues that are essential for understanding the research process.
