Claims

Correlations between individual gains in code practice and gains in the tests were generally small and positive, with the largest correlation for the code-translation test and a slight negative correlation for Test 5 suggesting interference between translating into and from code.

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? Rank correlations between percentage gain in code practice and test gains were small (largest 35±7 for Test 5), and the negative correlation on Test 5 argues for interference between the two directions of code translation. → Dearborn 1918

q2 · i? · causal · r1

Spearman footrule rank correlations computed from the class score tables. The article reports "but little relation" between practice gains and test gains, the largest being with translation from code, and a slight inverse relation (R = -3, ±7) between final practice record and final Test 5 record.

"The correlations under (I) show that there is, in general, but little relation between the individual percentages of gain made in the practice and those made in the tests. The largest correlation is with the translation from code tests."
