分析和实际模拟表明，在以正态分布进行抽样的前提下，合理选取抽样样本平均值和标准差，可使抽样效率进一步提高。
Theorical analysis and practical simulation indicate that if the samples are of normal distribution, the modelling efficiency can be increased further by using sensible parameters.
正态分布数据认为，样本中约68%的数值分布在距离平均值为1的标准偏差之内。
Normally distributed data assumes that about 68% of the values in the sample are within 1 standard deviation of the mean.
人口均值经常写成“x-条形柱”，如果你有一个样本有n个观测者，是从i=1到n和的xi/n，这是平均值。
The population mean is often written "x-bar." If you have a sample with n observations, it's the summation i = 1 to n of xi/n--that's the average.
方法采用贝塞尔统计方法处理样本数据，用Z比分数衡量一个实验室的检测结果与平均值的偏离程度。
Methods Besaier statistical method was chosen to process the data of the samples, Z-Score was chosen to evaluate the results and experimental deviation.
对于测试样本低于25以下时，几何平均值比中位数能更好的报告最佳任务完成时间中间值。
The Geometric Mean works better than the median for reporting the best middle task time for sample sizes less than 25.
6西格玛黑带应了解，根据所给量值(例如，平均值)是假设的，还是按样本估计的，在分析时需要不同的方法。
The Six Sigma Black Belt should know that different techniques are required for analysis depending on whether a given measure (e. g., the mean) is assumed known or estimated from a sample.
对基于不完备样本集的参数学习，则首先计算参数值的上限值和下限值，再利用某种策略，如平均值法，得到参数的最终估计值。
The upper limit and the lower limit is computed first when inducing the CPTs from uncompleted dataset, and the point value is estimated by some method such as averaging.
