Sex and prior training were compared with correct answers using the χ² test. Ages were compared with correct answers using ANOVA and t-test.
*Statistically significant difference between 7–8-year-olds and older children (ANOVA and t-test).
†Statistically significant difference between 13–14-year-olds and younger children (ANOVA and t-test).
‡Statistically significant difference between children with and without prior training (χ² test).
