The vocabulary tests section reports that Holley's and the writer's vocabulary scales show correlations of 0.4 to 0.6 with rate and comprehension, concluding vocabulary is "positively associated with reading ability" but inadequate as a measure.

"In the mass, knowledge of word meanings is positively associated with reading ability but the correlation is not sufficiently high to make a vocabulary test an adequate measure of it. The correlation of vocabulary and the composite of comprehension is 0.6 as compared to 0.8 for the Burgess test."
