1. Define clear objectives: To begin with, be sure of the purpose behind data analysis. 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.


2. Verify data quality and authenticity: During data mining, be sure of the authenticity of the source and the quality of the data. The outcome of your data analysis depends greatly on the quality of the data you are mining to derive relevant insights.

Get help from popular data analysis tools like Microsoft Power BI, Tableau, KNIME, and RapidMiner to name a few. Enroll in our industry-leading data analyst course to master the functionality of these advanced data analysis tools.


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.
