Technical Explanation
Missing data occurs due to various reasons, such as:
✅ Human Errors → Mistakes in data entry (e.g., missing survey responses).
✅ Corrupted Data → Errors during file transfer or storage.
✅ System Limitations → Sensors failing to collect readings.
✅ Data Privacy → Intentional removal of sensitive information.
Best Practices for Handling Missing Data
✅ Never delete rows if missing data is too frequent (use imputation instead).
✅ Use fillna() for small missing values (mean, median, or mode).
✅ Use SimpleImputer for advanced missing value handling in ML models.
✅ Use domain knowledge to decide the best imputation strategy.
