You can either have paperwork with diagrams with objectives in your notebook or maintain an Excel sheet for the same. This is a crucial process to ensure the relevancy of your data collection and avoid irrelevant data collection.

4. Abide by the data privacy policy: Privacy guidelines are one of the core principles of the data analysis process. Therefore, it is crucial for professionals to stick to legal considerations and ethical standards. A law-abiding data analyst must apply ethical measures while accessing data from unauthorised sources or breaches.

 

5. Implement the best data management practices: The ultimate task begins right after collecting the data, which is data management. You must organise your data efficiently to access it anytime you want.

 

6. Deploy data visualisation tools: Make data analysis easier and more understandable by leveraging advanced data visualisation tools. Mastering Power BI and Tableau would help.
