See this reference:
"Standard Error of Measurement (SEM): The amount an observed score is expected to fluctuate around the true score. For example, the obtained score will not differ by more than plus or minus one standard error from the true score about 68% of the time. About 95% of the time, the obtained score will differ by less than plus or minus two standard errors from the true score.
The SEM is frequently used to obtain an idea of the consistency of a person’s score or to set a band around a score. Suppose a person scores 110 on a test where the S.D. = 20 and [equation] = .91. Then:etc. etc."

Explanation: Standard Error (SE) - This is essential to assess how closely your sample relates to the population. By calculating the 95% confidence intervals () you can say that the population mean has a 95% chance of being ....
