Define expected goals (xG) in soccer and give one short worked example.

# Expected Goals (xG) **Expected Goals (xG)** is a statistical metric that measures the quality of a scoring chance by calculating the probability (0 to 1) that a shot will result in a goal, based on historical data from thousands of similar shots. Key factors include: - Distance from goal - Angle to goal - Type of assist (through ball, cross, etc.) - Body part used (foot, head) - Defensive pressure ## Worked Example **Scenario:** A striker receives a pass 12 yards directly in front of goal, with only the goalkeeper to beat, and shoots with his foot. **xG Calculation:** - Historical data shows that shots from this distance, angle, and situation result in goals approximately **35% of the time** - Therefore, this shot has an **xG = 0.35** **Interpretation:** Even if the striker misses, this was a high-quality chance worth 0.35 expected goals. Over a season, a team's total xG helps evaluate if they're creating good chances regardless of actual goals scored (which can be influenced by luck or exceptional goalkeeping).
