Here are some measurement terms you might see when looking at assessment results:
|Scores||The overall score for a student. Measurement scales can vary by assessment type and purpose, so scores will derive from the scale being used.|
Short for Standard Error of Measurement, this value is an estimate of a test’s precision. The smaller the SEM, the more precise the measurement.
Some tests will compare student scores with students from another group, such as a national “norm” sample. This value indicates how the student’s score ranks relative to his or her peers.
|Mean||The average score of students within this class.|
|Median||The middle score of students within this class.|
|Standard Deviation||This value indicates the variability of the scores from this class of students. A higher standard deviation typically indicates a wider range of scores.|
