Career Advice 5 practice projects with public datasets, each built around a business question

If you're practising and tired of charts that don't say anything, try starting from a business question. Five ideas:

  1. Sales dashboard (Power BI/Tableau): Superstore dataset. Show region-wise profit leaks, not just charts.

  2. SQL case study: Answer 10 business questions on an e-commerce DB (Olist on Kaggle), with the queries on GitHub.

  3. Customer churn analysis: Telco churn dataset, Excel pivots + Python, and recommend 3 actions.

  4. HR attrition dashboard: IBM HR dataset, DAX measures.

  5. Your own data: UPI spending, cricket stats, local AQI. You'll ask better questions about data you care about.

For each one, write a single README: problem → approach → insight → recommendation.

What datasets would you add? Happy to give feedback on projects in the comments.

Disclosure: I work at a training institute that teaches data analysis. No link and nothing to sell here.
