用法說明

precision 與 accuracy 的區別

  • precision 強調的是測量、描述或執行過程中的一致性、可重複性與細節的細緻度,即使結果可能偏離真實目標。
  • accuracy 強調的是結果與真實值或標準的接近程度,即正確性。
  • 一個結果可以是 precise but not accurate(精確但不準確),例如多次射擊都緊密地打在遠離靶心的同一位置。
  • 一個結果也可以是 accurate but not precise(準確但不精確),例如多次射擊平均落在靶心附近,但落點非常分散。

對比例句: EN: The measurements were of high precision, with all five trials yielding results within 0.01 mm of each other. 翻譯: 這些測量具有很高的精密度,五次試驗的結果彼此相差都在 0.01 毫米以內。

EN:The measurements were of high accuracy, each coming very close to the true value of 10.00 grams.

翻譯:這些測量具有很高的準確度,每一次的結果都非常接近 10.00 公克的真實值。

總結建議

在科學與工程領域,應同時評估 precision(數據的可重複性)與 accuracy(數據的正確性),兩者共同決定結果的整體品質。
