About
Statistical records detailing the performance of clubs during the La Liga 2021-22 Spanish football season. This resource was initially created to serve as a practical foundation for developing skills in Exploratory Data Analysis (EDA) and using tools such as Pandas. It offers analysts a detailed look at team performance, incorporating standard metrics like total points, wins, and goal differences, alongside advanced figures such as expected goals (xG), expected goals against (xGA), and possession percentages. The data was ethically scraped from a La Liga statistics website purely for educational purposes.

- GA: Goals conceded.
- GD: Goal difference.
- Pts: Total points accumulated.
- Pts/MP: Average points per match.
- xG: Expected goals.

Distribution
The data is structured as a CSV file, named
laliga21-22.csv, and is small, approximately 3.99 kB in size. It contains 19 records, with each record representing a team in the league. The original structure lists 35 columns, all of which contain valid data. Importantly, all 19 total values for every statistic are present, resulting in zero missing data.Usage
This dataset is highly suitable for introductory data analysis and skill development. It is an excellent resource for performing Exploratory Data Analysis (EDA), allowing users to visualise distributions and correlations between traditional performance metrics (like total points) and advanced metrics (like expected goal difference). It can be used by analysts interested in comparing the effectiveness of various La Liga clubs during the season, and it serves as a foundation for learning the basics needed to progress toward machine learning fields.
Coverage
The dataset focuses exclusively on the top-tier Spanish professional football league, La Liga. The data covers the entirety of the 2021-22 season. The statistics are aggregated at the club level and include metrics related to overall team performance, discipline (cards), and underlying player metrics (average age of the squad and number of different players used). All participating clubs from that season are represented.
