Median

A measure of central tendency that is the middle score, or the score for which 50% of scores fall above and 50% fall below. In a skewed curve or skewed distribution of test scores, the median is generally the most accurate measure of central tendency since it is not affected by unusually high or low scores.

Standard Error of Measurement (SEM)

The margin of error in an individual's score, representing the variability in scores if the test were administered multiple times.

Test-Retest Reliability

A measure of consistency where the same test administered to the same group of individuals at two different points in time produces similar results.
