What is Data Analytics?
Data Analytics is the process of examining, cleaning, transforming, and modeling data with the goal of discovering useful information, drawing conclusions, and supporting decision-making. In other words, it’s how organizations turn raw data into insights that help them understand patterns, trends, and relationships—so they can make smarter, evidence-based decisions.
Key aspects of Data Analytics:
- Collecting data from various sources (sales records, customer feedback, sensors, websites, etc.)
- Processing and cleaning data to ensure it’s accurate and usable
- Analyzing data using statistical, mathematical, or computational techniques
- Visualizing data through charts, graphs, and dashboards for easier interpretation
- Making predictions or recommendations based on the data insights
Why is Data Analytics important?
- • Helps businesses optimize operations and reduce costs
- • Improves customer understanding and experience
- • Identifies new opportunities and market trends
- • Supports strategic planning and risk management
In simple terms : Data Analytics = Turning raw data into actionable insights
