Learn Aggregating Team Statistics | Team Performance Analysis

As a coach, understanding the performance of your entire team is just as important as tracking individual athletes. Team-level statistics—such as average speed, total goals, or cumulative attendance—give you a clear picture of overall progress and reveal patterns that might not be evident from looking at single athletes alone. These metrics help you spot strengths, address weaknesses, and make informed decisions about training, strategy, and player selection. Without team-level insights, it’s easy to miss trends that could impact your team’s success.

# List of dictionaries representing each athlete's season goal tally
athlete_stats = [
    {"name": "Alex", "goals": 12},
    {"name": "Jordan", "goals": 9},
    {"name": "Taylor", "goals": 15},
    {"name": "Morgan", "goals": 8}
]

To analyze your team’s overall performance, you need to aggregate these individual statistics. Python’s built-in functions like sum and len make it easy to calculate team totals and averages. The total is simply the sum of all athletes’ values for a metric (such as goals), while the average divides this total by the number of athletes. These basic calculations are key for summarizing performance and comparing teams or seasons.


              1234567
            
# Calculate team average goals per athlete
total_goals = sum(player["goals"] for player in athlete_stats)
num_athletes = len(athlete_stats)
average_goals = total_goals / num_athletes

print("Team total goals:", total_goals)
print("Average goals per athlete:", average_goals)
