Table 2 Statistical comparison of the component scores of children and young adults when PCA is computed from all subjects

From: Narrow band quantitative and multivariate electroencephalogram analysis of peri-adolescent period

  Levene test: Mean comparison:
C1 (Beta - EMG) (F[1, 958] = 28.936), p < .001 (F[1, 705.346] = 6.488), p < .001
C2 (Delta - Theta) (F[1, 958] = 361.333), p < .001 (F[1, 561.066] = 32.359), p < .001
C3 (Alpha) (F[1, 958] = 48.738), p < .001 (F[1, 695.931] = 2.455), p < .014
C4 (Mu) (F[1, 958] = 6.373), p < .012 (F[1, 691.765] = −1.610), p < .108
C5 (Low Alpha) (F[1, 958] = 117.238), p < .001 (F[1, 522.495] = 2.954), p < .003
C6 (High Alpha) (F[1, 958] = 72.075), p < .001 (F[1, 741.052] = .975), p < .330
C8 (Low Delta) (F[1, 958] = 76.309), p < .001 (F[1, 728.777] = 4.176), p < .001
C9 (Mu) (F[1, 958] = 15.962), p < .001 (F[1, 917.456] = 1.842), p < .066
  1. The F values of Levene test (homogeneity of variances) and One-way ANOVA (two between-subjects levels: children and young adults) are displayed. The rhythms associated to each component are indicated from component 1 (C1) to component 9 (C9) . In the case of C1 the term Beta-EMG refers to the possible contamination of the Beta rhythm by electromyographic signals.
