Before diving into data analysis, the first and crucial step is to clean the data. Cleaning the data involves removing any irrelevant or duplicate information, correcting errors, and organizing the data in a structured format. This process ensures that the data is accurate and ready for analysis.

By cleaning the data in the initial stage, you can avoid drawing incorrect conclusions or making faulty decisions based on flawed data. It sets a solid foundation for the rest of the data analysis process, making it easier to extract meaningful insights and patterns.
