to 19 for the sample as a whole. When Patterson broke down the sample by level of peer-nominated aggression at age 8 into various percentile ranges (85th–89th, 90th–94th, and ≥95th), he found that a higher percentage (38.5%) of children who were rated by their peers as aggressive at or above the 95th percentile also were rated in the same range 10 years later compared with those children in the other two groups (32.0 and 32.3%). However, these differences in percentages are small and the analysis does not examine the continuity of aggression for those who scored below the 85th percentile.
