marginally significantp = 0.052
The significant interaction between SNR and musicianship reflects the appearance of somewhat lower (better) thresholds for the musicians than non-musicians at a 2.5 dB SNR and in quiet; post hoc testing revealed that these differences were marginally significant after correction (2.5 dB, F 1, 56 = 6.02, p = 0.052; quiet, F 3, 629 = 6.59, p = 0.052).
