Table 3 Test scores, junior and senior students

From: The acquisition and retention of ECG interpretation skills after a standardized web-based ECG tutorial–a randomised study

  Mean score (SD) Mean Δ score pre-test → post-test Mean Δ score post-test → retention-test Mean Δ score pre-test → retention-test
  Pre-test Post-test Retention-test*    
Junior students, N = 84 45.5 (15.7) 62.0 (10.6) 56.2 (9.8) 16.5 (p < 0.001) −5.8 (p < 0.001) 10.7 (p < 0.001)
Senior students, N = 119 57.8 (15.8) 72.9 (11.4) 62.5 (6.6) 15.1 (p < 0.001) −10.5 (p < 0.001) 4.7 (p < 0.001)
  1. *Pooled from follow-up intervals of all weeks (2–20 weeks).
  2. The mean test scores and standard deviations of the pre-test, post-test and retention-test are reported for junior and senior students. The mean delta scores between pre-test and post-test, post-test and retention-test and pre-test and retention-test, respectively, are presented with associated p-values.
