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: $$ SEM= SD*(\sqrt{1-ICC}) $$.
In layman's terms, the standard error of a data sample is a measurement of the likely difference between the sample and the entire population. For example, a study involving 10,000 cigarette-smoking adults may generate slightly different statistical results than if every possible cigarette-smoking adult was surveyed.he standard deviation of a data set is used to express the concentration of survey results. Less variety in the data results in a lower standard deviation. More variety is likely to result in a higher standard deviation. The standard error is sometimes confused with standard deviation.
