In an experiment on teen aggression and violent video games, some teens were driven to the study by their parents, while others drove themselves. It turned out that participants who were driven by their parents were generally more angry when they arrived (and thus exhibited a stronger relationship between aggression and video games), compared to participants who drove themselves. The issue of transportation to the study represents what potential problem?
A) random error
B) systematic error
C) sampling error
D) selection error

This represents a potential systematic error because the transportation method (parent-driven vs self-driven) may be related to the outcome variable (aggression and video games). This could impact the validity of the results and interpretation of the study.
