Part E: Worked Projects

This part presents complete case studies that integrate methods from earlier chapters. Each project includes background, research questions, data description, analysis with code and interpretation, sensitivity analyses, visualisations, and a discussion of findings and limitations. These examples demonstrate how to combine multiple techniques to address realistic small-sample research problems.
