sample distribution การใช้

• Such a procedure would involve the sampling distribution of the statistics.
• #Sampling distribution of a difference between two independent sample proportions
• This motivates other approaches, namely, other sampling distributions.
• Population 3 is the sampling distribution of the sampling mean.
• The concept of a sampling distribution is key to understanding the standard error.
• Each histogram is used to define a sampling distribution for the next pass.
• Populations 2 and 3 are virtual populations-conceptual devices to understand sampling distributions.
• As will be shown, the standard error is the standard deviation of the sampling distribution.
• This technique allows estimation of the sampling distribution of almost any statistic using random sampling methods.
• In other words, it is the standard deviation of the sampling distribution of the sample statistic.
• An advantage of this approach is that the sampling distribution of the odds ratio can be expressed exactly.
• The distribution of the mean age in all possible samples is called the sampling distribution of the mean.
• As the sample size increases, the sampling distribution become more narrow, and the standard error decreases.
• An RRT's vertices are selected in such a way that their distribution approaches the sampling distribution.
• Asymptotic theory does not provide a method of evaluating the finite-sample distributions of sample statistics, however.
• This is valid independently of the spatial sample distribution as long as the samples do not coincide in space.
• When drawing data from a sample, this means that the rejection region comprises 5 % of the sampling distribution.
• The graphs below show the sampling distribution of the mean for samples of size 4, 9, and 25.
• Then the problem can be characterized by choosing the sample distribution g that minimizes the variance of the scaled sample:
• This method has the advantage of not requiring that any assumptions be made about the shape of the sampling distribution.
