However, the meaning of SEM includes statistical inference based on thesampling distribution. SEM is the SD of the theoretical distribution of the sample means (the sampling distribution).1 Standard error estimates the likely accuracy of a number based on the sample size. Standard error of the ...
The standard error of the mean is designated as: σM. It is the standard deviation of the sampling distribution of the mean. The formula for the standard error of the mean is:where σ is the standard deviation of the original distribution and N is the sample size (the number of scores ...

In this post, I answer all these questions about the standard error of the mean, show how it relates to sample size considerations and statistical significance, and explain the general concept of other types of standard errors. In fact, I view standard errors as the doorway from descriptive st...
