🧪 Validity, Reliability & Reproducibility: What Every Computer Science Researcher Needs to Know

In computer science, we often focus on performance metrics: speed, accuracy, precision. But when it comes to research itself, especially when working with data, users, or algorithms, three deeper principles define the trustworthiness of our work: validity, reliability, and reproducibility. At Learn in Europe, we help early-stage researchers go beyond technical execution and develop rigorous scientific thinking. Understanding these core concepts is part of that foundation. Let’s unpack each one—and see how they shape high-quality research in computer science.

🧪 Theory Meets Practice: Understanding Theoretical and Empirical Research in Computer Science

Computer science is a field of dual identities. On the one hand, it’s abstract, mathematical, and conceptual. On the other, it’s deeply applied, data-driven, and user-focused. These two identities are reflected in the two primary modes of research in computer science: theoretical and empirical.
