Part 4: AI-Driven QA: Data Science Basics for QA Engineers

Welcome back! In this part of our AI-Driven QA series, we’re going to talk about something critical to AI and machine learning in testing — Data Science. Now, I know many QA engineers might feel a bit overwhelmed by terms like “data science” and “statistics,” but trust me, it’s simpler than it sounds, and you don’t need to be a data scientist to grasp the basics. Let’s walk through this step by step.

1. What is Data Science for QA Engineers?

Data science is the process of collecting, analyzing, and using data to make decisions. In our world as QA engineers, data is everywhere — test results, user feedback, logs, and more. By understanding data science, we can make our testing smarter and more effective.

• Why should you care? Because the better you understand data, the better your AI and machine learning tools will perform in testing.
• What are the basics? The key parts are:
• Collecting data
• Cleaning it up
• Analyzing it to find patterns

2. Collecting Data: The First Step

Before we can do anything fancy with AI, we need good data. Data is like the fuel for your AI models. Without it, you’re just guessing.

• Where does data come from in QA?
• Test results
• Application logs
