Sexual dimorphism in cheetahs

4.3.1 Sexual dimorphism 
Significant sexual dimorphism, with males being larger, was evident for all measurements recorded, and is summarized in Table 4.2. There was a significant difference between the mean weights of male cheetahs between years (F = 2.880, d.f. = 8, P = 0.007) but not for females (F = 1.136, d.f. = 8, P = 0.368)

Table 4.2 Morphometric data for the wild adult cheetahs (aged over 30 m at capture, and held in captivity for <30 days), collected using the protocol shown in Appendix IV. All measurements are in centimetres (cm), apart from body mass, which is measured in kilograms (kg). Statistical tests were conducted between the measurements for adult males and females to ascertain the degree of sexual dimorphism exhibited for each parameter. *Test 1 = independent samples t-test, with equal variances assumed (test statistic = t), and test 2 = Mann-Whitney U test (test statistic = z).
