当您参加测验时，就会出现答案和解释。

  1. 足球中的“预期进球”(xG) 指标是如何估算的？
    • 根据其特征，给定射门进球的概率
    • 球队本赛季实际进球数
    • 前锋应该支付的工资
    • 球员在一场比赛中跑动的总距离
  2. NBA在其Hawk-Eye合作伙伴关系中宣布的官方光学追踪技术合作公司是哪家？
    • Catapult Sports
    • Hawk-Eye Innovations, part of Sony Group
    • StatsBomb
    • The U.S. Department of Agriculture
  3. Catapult在其运动员监测系统中描述了哪些传感器输入？
    • Only jersey color and player name
    • Only event logs such as passes and shots
    • GPS or local-positioning data, inertial sensors and heart-rate data
    • Only the final score of a match
  4. NBA的防守压力评分使用光学追踪数据估算什么？
    • The probability a soccer shot becomes a goal
    • The athlete’s blood oxygen level during training
    • A team’s future draft position
    • The defensive pressure an opponent places on an offensive player
  5. Skinner和Guy提出了什么建模思路，用于从追踪数据学习篮球球员技能？
    • An offensive network model relating player skills to play success and lineup performance
    • A soccer shot-conversion model using only shot location
    • A biometric wearable classifier for injury diagnosis
    • A contract-value model based only on box scores
  6. What did a study of more than 50,000 NBA shot trajectories report about tight contests?
    • Contest level has no relationship to shot trajectory
    • Shooters tend to miss more often when their shots are tightly contested
    • Every contested shot is automatically blocked
    • Three-point shots never change under defensive pressure
  7. Which contextual factors does the StatsBomb xG description say may inform a shot’s expected-goal value?
    • Only the player’s jersey number
    • Only the final score of the match
    • Distance, angle, body part and contextual factors such as goalkeeper and defender positions
    • The team’s season budget
  8. What can optical tracking data provide beyond event records such as passes and shots?
    • Only the final match score
    • A medical diagnosis for each athlete
    • A guaranteed explanation for every tactical decision
    • Continuous player and ball positions over time
