Summary
The (hu)MANid software accurately classifies Native American mandibles. This study validated its effectiveness for forensic anthropology and NAGPRA compliance.
Area of Science:
- Forensic Anthropology
- Bioarchaeology
- Human Osteology
Background:
- The (hu)MANid software classifies mandibles by ancestry and sex using discriminant analysis.
- Replicability of its metric and morphoscopic variables is established, but external validation is limited.
Purpose of the Study:
- To test the accuracy of the (hu)MANid software for identifying Native American mandibles.
- To assess the software's utility in forensic and bioarchaeological contexts.
Main Methods:
- An independent sample of 52 Native American mandibles from the Great Lakes region was analyzed.
- Mandibles were processed using both linear discriminant analysis (LDA) and mixture discriminant analysis (MDA) within the (hu)MANid software.
Main Results:
- Linear discriminant analysis correctly classified 82.7% of mandibles as Native American.
- Mixture discriminant analysis correctly classified 67.3% of mandibles as Native American.
- The difference in classification accuracy between LDA and MDA was not statistically significant.
Conclusions:
- The (hu)MANid software demonstrates significant accuracy in identifying Native American skeletal remains.
- This tool is valuable for anthropologists in forensic investigations, biological profiling, and NAGPRA-related work.

01:12Analysis of Population Pharmacokinetic Data
300
Analysis of population pharmacokinetic data involves studying the behavior of drugs within diverse populations to understand their pharmacokinetic parameters. Traditional pharmacokinetic methods typically involve collecting samples from a few individuals and estimating these parameters. While these methods are commonly used, they have limitations in capturing the variability in drug response among individuals or heterogeneous populations. Population pharmacokinetics is employed to address these...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

01:11Statistical Analysis: Overview
6.7K
When we take repeated measurements on the same or replicated samples, we will observe inconsistencies in the magnitude. These inconsistencies are called errors. To categorize and characterize these results and their errors, the researcher can use statistical analysis to determine the quality of the measurements and/or suitability of the methods.
One of the most commonly used statistical quantifiers is the mean, which is the ratio between the sum of the numerical values of all results and the...

An analytical methodology can be divided into four sequential steps: technique, method, procedure, and protocol. A technique is a scientific principle that rationalizes a specific phenomenon through chemical measurements. Adapting a technique for analyzing a sample of interest is termed a method. The procedure outlines the directions for performing the analysis via an analytical method. The protocol is the detailed guidelines on the procedure, which should be strictly followed to obtain the...

01:12Statistical Methods to Analyze Parametric Data: ANOVA
440
Analysis of Variance, or ANOVA, is a powerful statistical technique used to analyze parametric data, primarily in research and experimental studies. It's designed to compare the means of two or more groups, assisting researchers in identifying any significant differences between these group means. There are two main types of ANOVA based on the complexity of the analysis: one-way and two-way.
One-way ANOVA is applied when a single independent variable or factor is scrutinized. It compares...
