Reporting & Basic Statistics
Data Wrangling (cleaning and preparing raw data)
ETL (Extract, Transform, Load) processes
- Common Tools:
SQL
Tableau
Power BI
Excel
Python (basic usage for analysis & visualization)
- Example Work:

Data Wrangling & ETL Processes
Big Data technologies
- Common Tools:
Python, R
TensorFlow, PyTorch
Scikit-Learn
Hadoop, Spark
- Example Work:
Building a predictive model for customer churn, training NLP models for sentiment analysis, or developing fraud detection algorithms.
3. Business Analyst
- Primary Role:
Works as a bridge between business and technology. They focus more on understanding business processes, stakeholder needs, and challenges, and then suggest data-driven solutions.
- Skills Required:
