The preciseness of this data depends upon a large number of factors such as the type of sampling algorithm used, the number of samples taken, and the skew of the data.
这种数据的准确性取决于很多因素，例如采用的抽样算法的类型、抽样的数量和数据的歪斜情况。

In summary, the accuracy of statistics depends on the sampling rate, the data skew, and data clustering for data sampling.
总之，统计信息的准确性取决于抽样率、数据倾斜(data skew)以及用于数据抽样的数据群集。

Then, we discuss jitter 's influence on Signal-to-Noise Ratio of data acquisition system and skew' s influence on consistency of orthogonal sampling of high speed acquisition system in detail.
