deviation
Meaning: The amount by which a single measurement or value differs from a fixed reference point, such as the mean. In statistics, standard deviation quantifies the spread of a data set.
Deviation is most commonly encountered in the phrase 'standard deviation,' a key measure of variability in statistics. Beyond mathematics, it also means a departure from an accepted norm or established course, as in 'deviation from the plan.' In technical contexts it collocates with 'standard,' 'mean,' and 'absolute.' The word carries a neutral tone in science but can imply disapproval when used about behaviour.
Examples
- The standard deviation of the test scores was remarkably low, suggesting consistent performance across the class. 测试成绩的标准差非常低,表明全班学生的表现相当一致。La desviación típica de las calificaciones fue notablemente baja, lo que sugiere un rendimiento uniforme en toda la clase.テストの点数の標準偏差は著しく低く、クラス全体で一貫した成績であることを示していました。시험 점수의 표준편차가 현저히 낮았으며, 이는 학급 전체에서 일관된 성적을 나타냈습니다.
- Any deviation from the approved protocol must be documented and reported to the supervisor. 任何偏离已批准方案的行为都必须记录并向主管报告。Cualquier desviación del protocolo aprobado debe documentarse y comunicarse al supervisor.承認されたプロトコルからの逸脱は、すべて記録し上司に報告しなければなりません。승인된 프로토콜로부터의 어떠한 일탈도 문서화하여 상사에게 보고해야 합니다.
- Researchers measured the deviation between predicted and observed values to assess the model's accuracy. 研究人员测量了预测值与观测值之间的偏差,以评估模型的准确性。Los investigadores midieron la desviación entre los valores predichos y los observados para evaluar la precisión del modelo.研究者たちはモデルの精度を評価するため、予測値と観測値の偏差を測定しました。연구자들은 모델의 정확도를 평가하기 위해 예측값과 관측값 사이의 편차를 측정했습니다.
