Statistical analysis of global amphibian trait data using the AmphiBIO database. Developed as part of the Statistics for Information Science & Technology course at the University of Nebraska Omaha.
Hihi!!!! :> This project explores statistical relationships between amphibian body size, reproductive mode, and habitat type using data from the AmphiBIO Global Amphibian Traits Database. It demonstrates the application of statistical inference methods to biological trait data.

This analysis prioritizes inference and interpretation over prediction. While robust methods were used to address assumption violations, the goal was not to build or tune predictive models.
Future work could explore phylogenetic structure, sensitivity analyses, or cross-validated models if the research question were expanded. These directions were deliberately beyond the scope of the present project.
