准确与精密 Accuracy and precision

(重定向自Accuracy)
一般射击结果为低准确度,低精密度;惟以枪只调校为目的的射击,则属于高准确度,低精密度。
高准确度,高精密度
低准确度, 高精密度
低准确度,低精密度

准确度英语:accuracy)与精密度(英语:precision)是在科学、工程学、工业及统计学等范畴上一个重要概念。

准确度是每一次独立的测量之间,其平均值与已知的数据真值之间的差距(与理论值相符合的程度)。例如:多次实验结果其平均值接近于已知的数据真值(理论值),可知道数据「准确」,或是数据具有「高准确度」;反之,平均值与已知的数据真值差距较大,表示实验数据不准确,或准确度不高。

精密则是当实验数据很精准时,会要求实验有高度的再现性,表示实验数据是可信的,也就是实验数据需要具有高精密度。(多次量度或计算的结果的一致程度)。

Accuracy and precision 准确与精密

(重定向自Accuracy)
Accuracy is the proximity of measurement results to the true value; precision, the repeatability, or reproducibility of the measurement
According to ISO 5725-1, Accuracy consists of Trueness (proximity of measurement results to the true value) and Precision (repeatability or reproducibility of the measurement)

Precision is a description of random errors, a measure of statistical variability.

Accuracy has two definitions:
