Definitions:

Raw Scores

The original, unaltered scores obtained directly from a test or assessment without any normalization or transformation.

Test-retest Reliability

This refers to the consistency of scores on a test or assessment when the same individuals take the test again under similar conditions after a time interval.

Interquartile Range

Provides the range of the middle 50% of scores around the median. Because it eliminates the top and bottom quartiles, the quartile range is most useful with skewed curves because it offers a more representative picture of where a large percentage of the scores fall.

Internal Consistency

A method of determining reliability of an instrument by looking within the test itself, or not going “outside of the test” to determine a reliability estimate as is done with test-retest or parallel forms reliability. Some types of internal consistency reliability include split-half (or odd-even), Cronbach’s Coefficient Alpha, and Kuder-Richardson.
