Expected Deliverables
- A DOC file that outlines your research methodology, segmentation strategy, and market basket analysis plan.
- An explanation of the relevant algorithms (e.g., K-means for segmentation, Apriori for association rules), including theoretical background and practical considerations.
- A comprehensive discussion on the implications for retail strategy and potential actionable insights.
Key Steps
- Conceptual Framework: Describe the concept of customer segmentation and the rationale behind market basket analysis in retail settings. Define hypothetical data scenarios based on public data insights.
- Methodological Approach: Detail how you would preprocess data, select features, and apply clustering algorithms for segmentation as well as association rule mining for market basket analysis.
- Insight Generation: Discuss the types of insights you could derive from the analyses, like identifying customer clusters or key product bundles.
- Reporting: Document all steps in a DOC file, providing detailed explanations, pseudo-code if necessary, and a discussion on the practical implications and limitations of your approach.
Evaluation Criteria
- Comprehensiveness in describing the segmentation and market basket analysis process.
- Sound justification for algorithmic choices.
- Clarity in conveying potential business insights and practical applications in retail.
- Overall structure, clarity, and detail provided in the DOC file.
Invest about 30 to 35 hours to thoroughly cover this task, ensuring you reflect both the analytical techniques and the business relevance in retail data science.
