Definitions for "Stanine"
A weighted scale divided into nine equal units that represent nine levels of performance on any particular test. The stanine is a standard score. Thus the intervals between different points on the scale are equal in terms of the number of correct test responses they represent. The mean is at stanine 5.
a statistical unit used in educational testing. Test scores are normalized (mathematically transformed) so that they have a mean ("average") of 5 and a standard deviation of 2. This tranformation naturally divides the ranked scores into 9 classes called stanines 1-9. The percentage of scores in each stanine is 4, 7, 12, 17, 20, 17, 12, 7, and 4, respectively. The technique originated in the U.S. military during World War II, and the word is a contraction of "standard of nine."
Indicates the relative standing of a student in comparison with the same reference group used for the percentile rank. Stanines of 1, 2, 3 are considered "below average," 4, 5, 6 are "average," and 7, 8, 9 are "above average." Return to the Top
