Subclaims¶

q2 i? By dividing practice between school and home conditions, the arithmetic practice effect was slightly negative in computation (second test 2.7 percent lower) and slightly positive in reasoning (second test 4.9 percent higher). → Heck 1914

q2 · i? · causal · r2

Methodological analysis within the arithmetic experiment: the author divided practice between school and home conditions to neutralize it, citing Schmidt's failure to weight the practice effect as the initial suggestion for the experiments.

"the average mark of all the students in the second computation test is 2.7 percent, less than that for the first, and the mark for the second reasoning test is 4.9 percent, more than that for the first."

• Home work in arithmetic can be done as well as school work, with overall differences close to zero — possibly the same claim (merge candidate)
