DATA CONCEPTS

In data dashboards and analytical reports, we often encounter a wide range of concepts. Some are instantly recognizable, while others appear abstract, overly technical, or disconnected from context. More often than not, our understanding of these terms is limited to surface-level definitions. Yet to read data accurately, to identify meaningful relationships, and to interpret what’s happening on the pitch, a deep understanding of these concepts is essential.

Unfortunately, comprehensive and accessible resources on these terms are scarce — both online and in traditional references. That’s precisely where this page comes in.

Data Concepts aims to fill that gap by offering in-depth explanations, practical examples, and detailed breakdowns of key statistical and tactical terms used in football analysis.

These articles are designed not only as a personal reference for myself, but also as a go-to resource for readers of this blog who want to better understand, interpret, and make use of football data. Because making sense of the numbers is one of the most rational ways to truly understand the game.

The duel ends when the ball moves away from both players. Read More...
