At 32 days, there was a trend toward larger relative brain weights for C57BL/6J vs. BALB/cJ mice, F(1, 80) = 24.3, p = 4.4 ?? 10???6 (Q(1,80) = 5.3, p = 0.04), but this trend was exaggerated by 6 outlying values (3 C57BL/6J females, 3 C57BL/6J males) that made the noneffects of the trimmed means analysis more trustworthy.
