Annotation

As part of a larger investigation into the use of macromorphoscopic trait data by forensic anthropologists to estimate ancestry from unidentified skeletal remains, the current study conducted a 14 year (2002-2016) intraobserver error study.

Abstract

Motivated by the development of a large macromorphoscopic database-which will potentially utilize data collected in 2002-quantification of observer error, the impact of technological improvements in macromorphoscopic trait data collection and observer experience is necessary. To maximize comparisons between the two samples, ten macromorphoscopic traits were assessed. Results revealed three patterns of error relating to observer experience, the introduction of new technologies, and error inherent in the method. Overall, this study found the effect of error on macromorphoscopic trait analysis could be predicted and did not significantly impact their utility. (publisher abstract modified)
