Data cleaning, also known as data wrangling, is a critical step in any machine learning or data science project. Without clean data, even the most advanced algorithms can produce misleading results.
Key Steps in Data Cleaning:
1. Handle Missing Values: Use techniques like imputation, removal, or placeholder values.
2. Remove Duplicates: Ensure your dataset doesn’t contain redundant entries.
3. Address Outliers: Detect and decide whether to keep, remove, or transform them.
4. Standardize Data: Ensure consistency in formats, units, and labels.
5. Fix Errors: Correct typos, inconsistencies, and data entry mistakes.
Why Data Cleaning Matters:
– Accuracy: Improves model predictions.
– Efficiency: Saves computational resources.
– Insights: Ensures trustworthy analysis and results.
