Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? The comprehension-mental age correlation is 0.10 in grade III and rises to 0.69 in grade VI. → Arthur I. Gates 1921
q3 i3 Correlations of the Burgess test with the Stanford-Binet increase from nearly zero in grade III to .56 in grade VI, a pattern also shown by the Thorndike-McCall with Stanford Mental Age. → Arthur I. Gates 1921

The article's summary reports the grade trend for Stanford-Binet mental age correlations with reading, noting "rises steadily to 0.69 in grade VI," while correlations among reading tests are as high in lower as higher grades.
"The correlations of mental age with comprehension in grade III is 0.10 which rises steadily to 0.69 in grade VI. The facts are similar for rate."

q3 · i3 · associational · r2
Cross-grade correlational analysis (Table XI and Table VIII) of reading tests with Stanford mental age measures across grades III-VIII. The article reports the Burgess-Stanford-Binet correlation rises from nearly zero to r = .56, with the same relation for the Thorndike-McCall.
"The correlations with the Stanford-Binet are interesting. They increase from nearly zero for grade III to .56 for grade VI. The same relation was revealed by the Thorndike-McCall test."
Discussion¶
Related Claims¶
- Correlation magnitude rises with the standard deviation of mental age of the group, so cross-group comparisons of the two traits are spurious — related
- Teachers' estimates show the highest single-measure correlation with the Stanford Revision (.72, 60 cases) — related
- The Burgess test correlates more highly with rate and comprehension composites (0.82 and 0.80) than any other single test, and pairs well with the Thorndike-McCall — related
- The Thorndike-McCall correlates about 0.50 with other single comprehension tests and 0.69 with a composite of group intelligence tests — related
- Practice effects on the Thorndike-McCall test over two or more hours of testing are very small — related
- Stanford-Binet mental age correlations with achievement rise with grade level, while verbal group test correlations stay about the same — a broader claim this one bears on
