- Abstract
- The discontinuation of traditional Verbal and Performance IQs in the WISC-IV and their replacement by four Indices lead to important modifications in practitioners' habits. The scatter analysis of the composite scores should be now considered in another way. In this paper, we advocate the use of the average index score as a baseline to analyze the Index score variability and to identify strengths and weaknesses in the profile of the Index scores. Davis's formula was used to compute reference values that can be used to highlight the Index scores significantly moving away from the average index score. The method was used for analyzing the Index score scatter in the standardization sample of the French adaptation of the WISC-IV. A rather important dispersion of the Index scores around the average index score was observed. More than 60% of the standardization sample showed at least one Index scores significantly moving away from the average index score. This variability was unrelated to gender, age and IQ level.
