第七章
可否請壞資料站出來？
Philipp K. Janert
在登山者與攀岩者之間流傳著一句話：「沒有所謂的壞天氣，只有不適當的穿著。」而任
何花了一些時間從事戶外運動的人都可以作證，在更有挑戰的環境中的旅程，往往是造
成回憶中最有價值的部分。但必須要是那些能夠讓自己處在那種環境的人才能體驗的。
基於相同的理念，我不認為有真正所謂的「壞資料」—只有不適當的方法。老實說，的
確有些資料集合是需要更多的工作來處理（因為遺失的資料、背景雜訊、編碼問題、不
方便的檔案格式等等），但它們並不構成基礎性的挑戰。只要給予足夠的努力，這些問
題便能夠被克服，並且也有許多有用的技巧可以用來處理這些狀況（如同在十一月底健
行時的保暖技巧）。
但基本上來說，這是屬於待在舒適圈的部分。若想要發現新的風景，就必須要能夠跟隨
未被做標記的小路，然後看它通往哪裡。或是相同的，當使用資料工作時，必須要有人
勇敢的對於資料能夠帶來什麼而提出建議，然後確認他是否是對的。請注意這是需要勇
氣的：僅僅描述別人所看到的會比提出新建議要安全許多，但這樣做會遺失很多能採取
的動作。
讓我們來檢視一些線索報告。之後，我們會重新組織，並且看我們學到了什麼。
