To compare the scores on two different subscales of an aptitude test, we would use the standard error of difference to determine if the difference between the scores is statistically significant. The standard error of estimate and standard error of measurement would not be appropriate in this situation, as they are used for different purposes. The standard deviation alone would not tell us if there is a significant difference between the two scores.
