Outlier Handling
โก๏ธ Detect anomalies using IQR, Z-score, or domain knowledge
โฌ๏ธ
Feature Engineering
โก๏ธ Create new meaningful features from existing data
โฌ๏ธ
Clean Dataset โ
โก๏ธ Ready for analysis, ML models, or dashboards

๐ก Reality Check:
If your data is not clean, your model is not smart.
Strong data cleaning = Strong foundation.

๐ฏ Pro Tip:
