Re: [外絮] NBA官方回應林書豪的影片事件
以下是不專業分析,有錯請大家海涵
原文中提到平均五百次犯規有一次惡意犯規,
那切入時得到惡意犯規是平均幾百次會有一次?
假設切入時,平均450次犯規有一次惡意犯規,
那八百次次犯規還沒有犯規,要怎樣看統計顯著度?
再假設,平均450次犯規一次惡意犯規,標準差算100好了,
814次犯規已經超過三個標準差
也超越就是常態分布上面的 0.0015的機率(上下加起來0.003)
統計顯著度已經很明顯了吧?
另外要談big data,那還得先把不同裁判,不同膚色的人相對應的犯規次數撈出來比較
只是這樣設及種族問題
他們應該也不敢去撈這樣的數據吧
以上是小弟的不專業分析,
可能有誤,請大家看看就好

: NBA denies officiating bias against Jeremy Lin
: The NBA responded to a New York Times article about a fan-made video showing
: Charlotte Hornets guard Jeremy Lin getting clotheslined, bumped and slapped
: during games without drawing a flagrant foul.
: NBA官方回應紐約時報撰寫關於粉絲製作林書豪影片的文章,影片中的林書豪在比賽時遭到
: 對手金臂勾、衝撞與打臉,可是卻沒有被判為惡意犯規。
: The six-and-a-half-minute video, titled Jeremy Lin: Too Flagrant Not to Foul,
: was posted to YouTube on April 5 and includes a letter to NBA commissioner
: Adam Silver suggesting the league and its officials had an anti-Jeremy Lin
: bias. Since the New York Times article on the clip was published on Thursday,
: the video has reached nearly 1.3 million views.
: 這一部約6分半的影片,標題打著 " Jeremy Lin: Too Flagrant Not to Foul "
: 在4月5日上傳至YouTube,其中包含了給NBA主席Adam Silver的一封信
: 暗示著聯盟和裁判對於林書豪有所偏見
: 而且自從紐約時報在星期四發表關於這部影片的文章之後
: 影片的觀看次數已經快要接近130萬了 (目前已突破133萬次)
: On Friday, the league responded with a statement. "After reviewing our
: extensive officiating database, we have found no data that suggests Jeremy
: Lin is disadvantaged by our officiating staff," the NBA said, citing the
: league's set of criteria on fouls.
: NBA官方在美國時間星期五正式發表聲明來回應
: 聯盟在聲明引用關於犯規的標準提到:「經過重新檢閱了大規模的數據資料庫之後,並未有
: 任何相關數據顯示出林書豪有遭到裁判的不平等待遇。」
: "While some of the plays in the video involved hard contact, none was
: subsequently deemed a Flagrant Foul given the full circumstances, angles and
: comparables from past games."
: "儘管在影片中一些play包含激烈的身體接觸,但是經過賽後完整的檢視,包括參酌整體
: 的情況、各種角度且與過去的賽事進行對比,後來都沒有被認定為惡意犯規。"
: The NBA also used leaguewide foul statistics, saying Lin ranked 21st among
: all players in drives to the basket with 1,537, but is seventh highest in
: drawn fouls among the 23 players with more than 1,500 drives.
: NBA也引用了整個聯盟的犯規統計數據,說林書豪在過去三個球季以來一共切入了1537次,
: 在NBA的所有球員中排名第21位
: 但是在23位超過1500次切入的球員當中,林書豪所吸引的犯規次數排行高居第七名。
: "Furthermore, given the infrequency of flagrant fouls (roughly 1 per every
: 500 foul calls), it is not statistically significant that none of Mr. Lin's
: 814 fouls drawn were deemed flagrant."
: 此外,就以惡意犯規的頻率來說 (大約500個犯規中,有一個惡意犯規)
: 林書豪則是在過去的814次犯規沒有出現過任何一次的惡意犯規
: 根據此一標準來看,並不具有統計上面的意義。
