## Overview

This is a portfolio of four reproducible SPSS coursework analyses, not a software application. The principal workflow is project data, SPSS syntax and analysis, then reported results and visualizations. Project READMEs document the analysis methods and outputs; source excerpts were not available, so links represent only this documented workflow.
