FAQ
What file formats will I receive in the final delivery?
You will receive the fully cleaned dataset in CSV or Excel format along with the complete Python code in a Jupyter Notebook file (.ipynb).
What Python libraries do you use for data cleaning and EDA?
I primarily use Pandas and NumPy for data cleaning and preprocessing, and Matplotlib along with Seaborn for exploratory data analysis and visualization.
How do you handle missing or duplicate data?
Depending on your dataset and requirements, missing values are either imputed using mean, median, mode, or dropped, while duplicates are completely identified and removed to ensure data integrity.
Can you handle large datasets?
Yes, Python handles large datasets very efficiently. If your dataset is exceptionally large, please drop me a message beforehand so I can review it.
