What are the qualitative descriptions for subtest scores? In the past I have used 8-12 for the Average range, 6-7 Low Average and 13-14 for High Average.
We don’t have subtest descriptors in the manual. The range of subtest scaled scores (1-19) does not allow for fine discrimination between scores when they are converted to percentile ranks (note the gaps in the percentile ranks for the descriptions Jerry Sattler uses in his book, below). That is why our manuals only report descriptive classifications for the composite scores, which have a much broader range that allows for finer discrimination between scores. These are Sattler’s descriptors, not Pearson's. For three categories of descriptors: Scaled score from 1-7 is described as a weakness or below average with a corresponding percentile rank of 1-16. Scaled score from 8-12 is described as average with a corresponding percentile rank of 25-75. Scaled score of 13-19 is described as a strength or above average with a corresponding percentile rank of 84-99. (page 115, Table 4-1). For five categories of descriptors: Scaled score from 1-4 is described as exceptional weakness, very poorly developed, or far below average with a corresponding percentile rank of 1-2. Scaled score from 5-7 is described as weakness, poorly developed, or below average with a corresponding percentile rank of 5-16. Scaled score from 8-12 is described as average with a corresponding percentile rank of 25-75. Scaled score from 13-15 is described as strength, well developed, or above average with a corresponding percentile rank of 84-95. Scaled score from 16-19 is described as exceptional strength, very well developed, or superior with a corresponding percentile rank of 98-99.
Looking back on my old testing and something isn't adding up. I have superior processing speed, below average working memory. But above average matrix reasoning. How is that possible? What does it mean.
If a child verbally states and points his responses on Picture Span, are the results still valid due to verbally stating each response and also pointing?
What happens when all scores are on the lowest scoring but 1 score is average bringing the total score to borderline scoring? I don't feel this is a accurate overall
They specifically refused to give an overall score for my testing because I ranged from low average to superior. Saying it would 'likely reflect an invalid representation of overall abilities'.

What affects the critical value of an index comparison? How does it correlate with base rate?

What is DSs, digit span sequencing?
What are the subscales?
