ANOVA table for vibration frequency.

ANOVA table showing the results of the repeated-measures two-factor analysis of variance, demonstrating the effect of species and angle of orientation on frequency of whisker vibration. A significant effect of angle of orientation and a significant interaction is observed. No significant effect of species is observed. Sample size for statistical tests was n = 8 for California sea lions; n = 8 for elephant seals; and n = 6 for harbor seals at all angles of orientation.
