The Data Analysis Workflow

Data analysis isn’t just about numbers — it’s about transforming raw information into meaningful insights.

To achieve this, analysts follow a structured process that reduces guesswork and ensures results are consistent and easy to explain.

Without a clear process, it's easy to:

• Miss important issues in the data
• Draw incorrect conclusions
• Waste time fixing preventable mistakes
• Lose the trust of your team or client

A good workflow brings structure to your thinking and allows you to communicate your process clearly to others.

In this course, we'll guide you through each major step:

1. Ask a Question: What are we trying to learn or solve?
2. Collect Data: Where can we get reliable data?
3. Clean the Data: Fix inconsistencies, missing values, and errors
4. Analyze the Data: Explore patterns and test hypotheses
5. Visualize and Share: Turn findings into clear, impactful visuals

These stages form the core workflow of real-world analytics — an iterative process you’ll revisit throughout this course.
