Educational Measurement and Evaluation

Notes • Stanine scores are those converted scores of raw scores of which the mean (M) is 5 and
σ
standard deviation () it 1.96. For it, the raw scores are divided into 9 unit-groups and they
are displayed on a 9-point scale from 1 to 9.

• Stanine scores can be obtained using any of C-scores, percentile rank (PR) and T-scores. We
have already discussed the methods of calculating C-scores, percentile ranks (PR) and
T-scores.

• Only 9 numbers are used in Stanine, while 11 in C-score. So the analysis of these scores is
easier than those of C-scores. The meaning of Stanine scores is generally taken as follows.
• A percentile score is another type of converted score. Your raw score is converted to a
number indicating the percentage of the norm group who scored below you.
Percentiles can not be averaged nor treated in any other way mathematically. However
they do have the advantage of being easily understood and can be very useful when giving
feedback to candidates or reporting results to managers.
