查询词典 sampling error

Sampling error or allowable error is conventionally accepted between 1% and 10%; however, it is suggested that sampling error should be carefully assessed in light of the nature of the derivation of the population proportion and other aspects of the initial data.

抽样误差或允许误差是接受常规的1 ％和10 ％，但是，有人建议，抽样误差应当认真评估根据的性质推导的人口比例和其他方面的初步数据。

The computer simulated sampling points with different grid cell sizes were generated and then interpolated into 10000 points with inverse distance weighted. Finally, the original value was compared with the interpolated value for the same grid cell to find the sampling error, and optimal sampling points were determined according to the allowable sampling error.

利用计算机按照不同的网格单元尺寸(如3×3，5×5，7×7等)进行采样，之后利用采样值进行IDW插值处理，将数据点恢复到原始的10000个，并把插值结果与原始值进行比较即可得到采样误差。

The main research and application result is: five dynamic sampling frames with spatial autocorrelation analysis are achieved such as high-high, low-low, high-low, low-high and not significant, and finally the result of per capita agricultural total output value of Beijing with spatial stratified sampling technique is 35.80 thousand Yuan RMB, with the sampling error range is ±3.861 thousand Yuan RMB.

其结果为：动态生成"高－高集聚"、"低－低集聚"、"高－低集聚"、"低－高集聚"和"分布不明显"5个抽样框，并最终通过空间分层抽样流程得到北京市人均农业总产值的抽样调查结果为3.580万元，抽样误差的允许范围为±0.3861万元。

For results based on the total sample of national adults, one can say with 95% confidence that the maximum margin of sampling error is ±2 percentage points.

对于结果的基础上，总样本国家的成年人，一可以肯定地说， 95 ％的信心，最高幅度，抽样误差是± 2个百分点。

According to a CNN/Opinion Research Corporation survey released Monday, 51 percent of the public consider China a military threat, with 47 percent disagreeing. That 4-point margin is within the poll's 4.5 percent sampling error.

根据CNN/观点研究公司周一发布的数据，51％的民众认为中国是一个军事威胁，而47%的民众对此不予认可。4％的误差率正好处于该项民意调查的4.5％的抽样误差率中。

We can get around this problem unknown sampling error to a large extent if we use probability sampling, since we can get estimates of the sampling error from the sample itself.

偶们可以处理这个难题未知的抽样误差在非常大程度上假如我们用概率抽样，因为我们可以从样品本身的抽样误差估计。

Those 48,000 viewers could be a rounding error caused by the change in channel position (although CNN lost in a couple of months to MSNBC before the channel switch) or to sampling error.

这48，000名观众的差距可能是频道位置变化引起的误差（虽然CNN在频道位置变化的几个月前就落后于MSNBC了）或者是抽样误差。

Sampling error and non-sam pling error.

差和非抽样误差的影响。
