About

Small Sample Size tests one baseball number at a time. Each post makes a claim, shows the chart, explains the method in plain terms, names the caveats, and ends with a verdict.

Every analysis is built with AI: Claude Code does the work, and the free bbdata CLI pulls the data from Baseball Savant and the MLB Stats API. Every number is checked against a second source before it's published.

Aaron Reales writes it, and teaches the same workflow in a course for baseball analysts.
