Standard Error of the Mean and Standard Error of the Difference
Please give a full explanation of the difference between a standard error of the mean and a standard error of the difference between means.
Solution Preview
The standard error of the mean is the margin or error by which the mean (average) of a number of samples taken from the same population. This error may cause the mean to be slightly off ...
