Median reaction time

Ambidextrous Left-handed Right-handed
Girls 0.44 0.44 0.44
Boys 0.39 0.40 0.39
Notes: Elementary students only. In the question for elementary school, we did not specify with which hand students should test their reaction time. It is probable that right-handed students used their right hand, and left-handed students, their left.
