There are 3 ways to calculate SEM. Also it is important if you want to have SEM agreement or SEM consistency. I will show you the SEM calculaton from reliability. First you should have ICC (intra-class correlation) and the SD (standard Deviation). Then you calculate SEM as follows: $$ SEM= SD*(\sqrt{1-ICC}) $$.
The standard error of the mean is the standard deviation of the sampling distribution of the mean. It is therefore the square root of the variance of the sampling distribution of the mean and can be written as: The standard error is represented by a Ï because it is a standard deviation.
