ANOVA

The type of game significantly affected injuries, *F*(1, 36) = 25.86, *p* < 0.001,  = 0.383, but the type of console did not, *F*(1, 36) = 3.58, *p* = 0.067,  = 0.061. The effect of the type of game was significantly moderated by the type of console, *F*(1, 36) = 5.05, *p* = 0.031,  = 0.092. Conditional post hoc tests and the Descriptives plot (@fig-13_a) revealed that injury severity was statistically comparable for static games, *t*(36) = 0.251, ptukey = 0.803, d = 0.112 (95% CI [-1.137, 1.361]), but was significantly higher for Nintendo switch compared to Xbox for active games, *t*(36) = -2.927, ptukey = 0.006, d = -1.309 (95% CI [-2.63, 0.012]).
