What is the impact of stadium attendance on the match outcomes in professional football?

This project analyses the impact of stadium attendance on match outcomes in professional football, focusing on LaLiga. The main research question is: What is the impact of stadium attendance on match outcomes in professional football? The dataset has been constructed at match level and integrates sports performance variables with attendance related in order to evaluate whether fan presence reinforces home advantage. The study includes three nonconsecutive seasons (2005/06, 2014/15 and 2023/24), allowing a temporal comparison across different competitive contexts. This dataset provides a structured and integrated framework for analysing how environmental factors such as fan attendance may influence sporting performance. It is particularly useful for studies on home advantage, sports analytics, and applied data management in professional football
