命中条纹不遵守你的规则:命中条纹不仅仅是随机变化的副产品的证据
Hitting Streaks Don't Obey Your Rules: Evidence That Hitting Streaks Aren't Just By-Products of Random Variations
摘要:
在美国职业棒球大联盟中,击球的次数比我们预期的要多。从1957年到2006年,美国职棒大联盟击球手的所有击球线被随机排列10,000次,并测量了每个长度从2到100的击球条纹的数量。然后将每个长度连胜的平均计数与现实生活中的相应总数进行比较,当游戏按时间顺序排列时。现实生活中的条纹数量明显高于随机排列。删除了非开始(如捏击外观),因为这些可能会过度减少排列中的条纹数量;排列中的条纹数量增加,但仍显着低于现实生活中的总数。可能的解释是为什么更多的条纹出现在现实生活中比我们预期的,包括可能的热手的想法。联系trentm@email.unc.edu
英文摘要:
There have been more hitting streaks in Major League Baseball than we would expect. All batting lines of MLB hitters from 1957-2006 were randomly permuted 10,000 times and the number of hitting streaks of each length from 2 to 100 was measured. The average count of each length streak was then compared to the corresponding total from real-life, when the games were in chronological order. The number of streaks in real-life was significantly higher than over the random permutations. Non-starts (such as pinch-hitting appearances) were removed since these may be unduly reducing the number of streaks in the permutations; the number of streaks in the permutations increased but was still significantly lower than real-life totals. Possible explanations are given for why more streaks have appeared in real-life than we would expect, including possibly the hot hand idea. Contact at trentm@email.unc.edu
