Shape 1. The Mean The mean of the distribution of sample means is the mean of the population The mean of the distribution of sample means is called expected value of X X is an unbiased estimate of µ: on average, the sample mean produces a value that exactly matches the population ...
The Distribution of Sample Means The Distribution of Sample Means Definition: the set of means from all the possible random samples of a specific size (n) selected from a specific population Theoretical distribution Central Limit Theorem 1. The mean of the distribution of sample means is called ...
mean=平均值 proportion=比例 sampling distribution of the sample mean 样本均值抽样分布 样本均值的抽样分布即所有样本均值的可能取值形成的概率分布。例如，某高校大一年级参加英语四级考试的人数为6000人，为了研究这6000人的平均考分，欲从中随机抽取500人组成样本进行观察。若逐一抽取全部可能样本，并计算...

For the sampling distribution of sample means, what is the relationship between the population mean and the mean of all possible sample means of size 25?? They are different by one standard error of the mean.They are not equal.They are both normally distributed.They are equal. 相关知识点: ...
It i s well known that even if the sample observations are correlated and not normal, the sample mean is normal in 1arge samples. But how large is large? This question i s investigated in this paper. In particular , the relation between the rate of convergence and the correlation property...
