  1. p 1 = Between IG and CG at baseline.
  2. p 2 = McNemar, (within IG and CG).
  3. p 3 = Chi-square for independence (between IG and CG), IG = Intervention group, CG = Control group.
  4. Significant improvement = p < 0.01 marked with bold font. Significant improvement = p < 0.01 because of repeated tests. Effect size measured by Cramer’s V.
  5. % = Percentage of correct answer.
