The most accurate single indicator was sacrum shape (94.1%). On the other hand, three combinations of pelvic criteria produced higher levels of accuracy than the trait list as a whole: obturator foramen shape and presence of the ventral arc (98%); obturator foramen shape and presence of the ventral arc (98%); obturator foramen shape and true pelvis shape (98%); pubic shape and acetabulum shape and size (95%).
The William Bass Field Manual mentions other studies of European populations, but reproduces in full several tables by Rogers and Saunders based on 49 “adult skeletons from a 19th-century cemetery located on the grounds of the St Thomas Anglican Church in Belleville, Canada.”
Embedded below are tables for:
Table 3-24. Accuracy Levels for Each Individual Pelvic Trait (after Rogers & Saunders (1994:1051, Table 5) (Bass 2005: 216)
Table 3-25. Probability of Estimating Sex Correctly for Combinations of Two Traits (after Rogers & Saunders (1994:1051, Table 3) (Bass 2005: 216)
Curious about what the broad labels for male and female anatomical regions are for those anthropologists using the Bass Manual?
