Data Science is a field that focuses on extracting meaningful insights from data using a combination of mathematics, statistics, and programming.
At its core, Data Science answers three types of questions:
- What happened? (Descriptive Analysis)
- Why did it happen? (Diagnostic Analysis)
- What will happen next? (Predictive Analysis)
A Data Scientist does not just “look at data” — they:
- Collect raw data from multiple sources
- Clean and structure it
- Analyze patterns
- Build models to predict future outcomes
📊 Real-world thinking:
If an e-commerce company sees sales dropping:
- Data Analysis tells when it dropped
- Data Science explains why it dropped and predicts what will happen next
