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: $$ SEM= SD*(\sqrt{1-ICC}) $$.
Standard Error of the Estimate. A related and similar concept to standard error of the mean is the standard error of the estimate. This refers to the deviation of any estimate from the intended values. For a sample, the formula for the standard error of the estimate is given by: where Y refers to individual data sets, Y' is the mean of the data and N is the sample size. Note that this is similar to the standard deviation formula, but has an N-2 in the denominator instead of N-1 in case of sample standard deviation.
