Outliers are data points that significantly differ from the rest of the dataset. They can skew results and affect statistical analyses. To handle outliers, you can:

1. Identify them using methods like the IQR (Interquartile Range) or Z-scores.
2. Remove them if they are errors or irrelevant.
3. Transform them using techniques like log transformation.
4. Use robust statistical methods that are less affected by outliers.
5. Analyze them separately if they provide valuable insights.

Normalization is the process of organizing data in a database to reduce redundancy and improve data integrity. The main types of normalization are:

1. **First Normal Form (1NF)**: Ensures that all columns contain atomic values and each entry in a column is of the same type.
2. **Second Normal Form (2NF)**: Achieves 1NF and ensures that all non-key attributes are fully functionally dependent on the primary key.
3. **Third Normal Form (3NF)**: Achieves 2NF and ensures that all non-key attributes are not only dependent on the primary key but also independent of each other.
4. **Boyce-Codd Normal Form (BCNF)**: A stronger version of 3NF that deals with certain types of anomalies not handled by 3NF.
5. **Fourth Normal Form (4NF)**: Achieves BCNF and addresses multi-valued dependencies.
6. **Fifth Normal Form (5NF)**: Achieves 4
