1·One is to compare the sample mean and the sample variance.

当样本均值大于样本方差时，认为是服从二项分布；

2·Populations, random samples. Sample statistics, moments of the sample mean and variance.

母体， 随机样本。 样本统计， 样本平均数和变异数的动差。

3·We can define it in a couple of different ways depending on whether we're talking about sample mean or population mean.

我们有几种不同的方式去定义这个概念，取决于我们指的是，样本均值还是总体均值。

4·By using the sample mean range( R )instead of standard deviation of the sample( S )inS method, theR method is obtained in this paper.

在“S”法的基础上，利用样本平均极差R代替“S”法中的样本标准差S ，从而得到了“R”法，并且给出了相应的样本大小，及各种情况下的接收标准。

5·In this paper the method on T2 control chart, by which the sample mean vectors of several related quality characteristics are controlled simultaneously in a process, is introduced.

介绍了工序中同时控制多个相关质量特性均值向量的T2控制图方法。

6·The second question to ask is whether the sample is representative? See what I mean?

第二个要问的问题是，样本是否有代表性？明白我的意思吗？

7·Normally distributed data assumes that about 68% of the values in the sample are within 1 standard deviation of the mean.

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。

8·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.

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。

9·See the sample configuration file included with the utility for detailed instructions about what the various configuration parameters mean.

有关各个配置参数的含义是什么的详细说明，请参见该实用工具包括的示例配置文件。

10·In contrast, the attractive men in the NCDS sample have a mean IQ of 105.00, and the unattractive men have a mean IQ of 91.39.

与之相反的是，在抽查中，有魅力的男士平均智商是105.00，没有魅力的男士平均智商是91.39。
