Accuracy（准确性）和Precision（精确性）是统计学中两个重要的概念，它们表示数据测量结果的不同方面。虽...
Accuracy and Precision difference (准确度与精度)Accuracy: The degree of conformity of a final measured value, with respect to the true value as defined by accepted standard (the “truth”).（准确度：最终测量值，相对于被公认的标准定义的真实值的一致程度）Precision: The degree of refinement in ...
they are. Looking at the process of measurement more carefully, you will see that there is another important consideration: precision. Matt Anticole explains what exactly precision is and how can help us to measure things better. 当我们测量事物的时候,大多数人只关心他们得多准确,或者多接近准确值...
Accuracy准确度is the difference between the measured value and the true value of a tested material.Precision精确度is the repeatability of successive measurements under the same conditions.测量的精密度、准确度和精确度 这是人们在测量中常常容易混淆的三个名词，虽然它们都是评价测量结果好坏的，但涵义有较...

准确度 Accuracy 预测正确的比率。 是一个整体的特征。 精确度 Precision 例如数学上的小数点的精确概念, 越是精确,说明度量的结果很稳定,不会有较大的偏差。 但仅仅是对测量结果的刻画,跟真值没有任何关系。 What Is the Difference Between Accuracy and Precision?
