Two Types of Tables for Use with the Stanford Binet Intelligence Scale: Fourth Edition

Abstract

Confidence intervals for the Stanford Binet Intelligence Scale: Fourth Edition were computed for the Verbal Reasoning SAS, the Quantitative Reasoning SAS, the Abstract/Visual Reasoning SAS, the Short-Term Memory SAS, and the Composite SAS. These intervals were computed separately for each age group using the 90% and 95%7o levels of confidence. The differences required for significance among the Area SASs and between the Area SAS and Composite SAS were computed for the .05 and .10 levels of significance. In addition, the differences necessary to determine that subtest scaled scores are significantly different from the mean of the respective areas were calculated for the .05 and .10 level. The Bonferroni t inequality was used to control for multiple comparisons. All values were computed using the standard errors of measurement for the standardization sample reported in the Technical manual. The use of the tables in interpreting test scores is discussed.
