Accuracy 和 Precision有什么不同？

Based on Wikipedia, the accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's actual (true) value. The precision of a measurement system, also called reproducibility or repeatability, is the degree to which repeated measurements under unchanged conditions show the same results.

同上，我估计精确比准确还强悍那种…
