- Customer segmentation using RFM analysis (Recency, Frequency, Monetary)
- Predictive modeling for sales forecasting
- Basket analysis for product recommendation
- Seasonality and trend analysis
Tools for Retail Dataset Analysis
Common tools include:
- Microsoft Excel or Google Sheets for basic analysis
- Python with libraries like Pandas, Matplotlib, Seaborn
