dsh-quartiles

Quartiles are one of the most basic yet most frequently needed statistics in everyday data work, yet hand-calculating them invites small errors and spinning up a standalone script adds an unnecessary context switch. dsh-quartiles slots quartile computation directly into your dsh session: invoke the registered tool once in conversation and the result comes back immediately, without ever leaving the current window.

The plugin is a pure Node.js implementation with zero network calls and no third-party runtime dependencies. Its logic is fully self-contained and ready to execute the moment it loads. After installation it registers a tool in the session; pass in your data and receive quartile statistics entirely offline, which makes it a natural fit for air-gapped or intranet environments where external services are unavailable.

It suits data analysts who need a quick sanity check on a dataset, educators who want to demonstrate quartile calculations live in front of students, and anyone who prefers a lightweight, dependency-free way to get basic descriptive statistics right inside the conversation flow. No configuration, no setup overhead — install and go.
