Table 1 in Sexual Dimorphism In The Ringtail (Bassariscus Astutus) From Texas

Table 1. Comparison of cranial and dental measurements (in mm) between sexes of adult (age classes 2, 3) ringtails (Bassariscus astutus flavus) from Texas. Descriptive statistics are: sample size (n), mean, standard deviation (SD), minimum and maximum measures, confidence intervals (C.I.), and coefficient of variation (CV). Probability values (P) derived from one-way ANOVAs; non-significant results indicated by n.s. Sex (n)Mean ± SDMinimum-maximum95% C.
