影响抽样误差大小有很多因素，如标志变异程度，样本单位数量的多少，抽样方式方法的选择等。
There are many factors that influence the sampling error, such as, extent of mark variation, amount of sample unit and the choice of sampling method, etc.
变异性中占比例最大的设备误差是血压计袖套的大小。
The instrument error that contributes to the greatest variability is the cuff size of the sphygmomanometer.
本文主要对这种新型传动齿轮——斜航式法向圆弧螺旋锥齿轮的误差与变异的关系和精度检测进行了较为深入的理论研究。
In this dissertation, the relationship between the errors and variations for the loxodrome normal circular-arc spiral bevel gear (LNCSBG) is deeply studied.
这个指标描述了由异质性而非抽样误差引起效应变异的百分比。
This describes the percentage of the variability in effect estimates that is due to heterogeneity rather than sampling error (chance).
相同条件下多次采集的数据变异系数<4%，说明该系统操作具有可重复性；检测结果最大相对误差为4.4%，满足微量组分检测的准确度要求。
Using this system, the chroma values of ten samples can be obtained once and the variable coefficients are lower than 4% and the maximum of relative errors is 4.4%.
研究者对抽样误差的影响估计不足，所谓F2株系的小样本抽样，又进一步缩小了株系内变异程度，这就有可能出现假阳性的结果。
Researchers neglected the influence of sampling error, and small samples from F2 populations further reduced the variation. These deficiencies may result in wrong conclusions.
