Montreal Battery of Evaluation of Amusia (MBEA) test scores for the six subtests and average score in the study by Peretz et al. (2003, p. 66).
| Scale | Contour | Interval | Rhythm | Meter | Memory | Average | |
|---|---|---|---|---|---|---|---|
| Mean correct responses | 27 | 27 | 26 | 27 | 26 | 27 | 27 |
| SD | 2.3 | 2.2 | 2.4 | 2.1 | 2.9 | 2.3 | 1.6 |
| Cut-off score (mean – 2 SD) | 22 | 22 | 21 | 23 | 20 | 22 | 21.6∗ |
| Cut-off in % | 73.3 | 73.3 | 70 | 76.7 | 66.7 | 73.3 | 72.2∗ |
| Participants with perfect score (%) | 17 | 9 | 7 | 15 | 14 | 10 | 3 |
| Participants below cut off (%) | 3 | 1 | 1 | 1 | 1 | 1 | 2 |
∗Peretz et al. (2003, p. 69) list an average cut-off score of 23 and a cut-off percentage of 78%, which is probably due to a rounding error (see Wise, 2009, p. 115).
