Developed and delivered a comprehensive statistics module for the Dafny standard libraries, adding formally verified functions for mean, median, mode, variance, and standard deviation. This work, integrated into the dafny-lang/dafny repository, focused on expanding analytics capabilities within verified Dafny codebases and reducing reliance on external math libraries. Leveraging Dafny for formal verification and C# for supporting components, the module ensures correctness by construction in statistical computations. The approach emphasized rigorous specification and proof, enabling safer data analysis workflows. During this period, the primary focus remained on feature delivery and verification, with no major bug fixes addressed alongside the new functionality.
