standard error 什么是统计学中的Standard Error ( SE )? 我们来看一段英文解释:The standard deviation of a sampling distribution is called as standard error. In sampling, the three most important characteristics are: accuracy, bias and precision. Standard Deviation:缩写为SD或者S,中文翻译为标准差或者...
补充(答主同链接基础上):standard error似乎原初的名字是“The estimated standard deviation of sampling distribution of x-bar”,也不知道从谁开始把这个"deviation"用“error”简写了。 “As for the name, the full name is "The estimated standard deviation of the sampling distribution of x-bar"; it on...

standard error Also found in:Thesaurus,Medical,Legal,Financial,Acronyms,Encyclopedia,Wikipedia. Related to standard error:variance standard error n. A generalized notion of standard deviation, used to characterize the dispersion of a statistic (such as the sample mean) calculated from randomly sampled ...
Standard error is used to estimate the efficiency, accuracy, and consistency of a sample. In other words, it measures how precisely a sampling distribution represents a population. It can be applied in statistics and economics. It is especially useful in the field of econometrics, where researcher...
Standard Error in Statistics - Learn about Standard Error in Statistics, its definition, significance, and how to calculate it effectively.
Larger sample sizes have narrower sampling distributions. Since n is in the denominator of the Standard Error formula, as n increases Standard Error decreases. Again, decreases in Standard Error correspond to narrowing of the sampling distribution. Again, this reflects lower uncertai...
Standard error is intuitively the standard deviation of the sampling distribution. In other words, it depicts how much disparity there is likely to be in a point estimate obtained from a sample relative to the true population mean. What Is a Good Standard Error? Standard error measures the amou...
