## Overview

This repository is a small collection of statistics lesson notebooks and CSV datasets. The filenames identify topics and available data, but with no README or source excerpts, how the datasets are used—and how a learner proceeds through the lessons—cannot be established. The graph therefore shows the lesson and dataset artifacts without guessing at their connections.
