January 01, 2010 - The sample mean and standard deviation are usually
denoted by and s, respectively. … The standard deviation of this (theoretical) distribution of means is called the “standard
error” of … Therefore, the
standard error of the mean is zero. … If the data comprise the entire finite population then the standard error is zero. … Therefore, an estimate of the standard error should be incorporated into the
regression.
