Evidence¶

Lin 2013¶

Lin, Ching-Ying & Hsu, Wei Shu. (2013). Effects of Hierarchy Vocabulary Exercises on English Vocabulary Acquisition. English Language Teaching, 6(9). doi:10.5539/elt.v6n9p110

q2 · i3 · causal · r1

Correlational analysis of the same 56 students' immediate vocabulary and reading comprehension scores. Both correlations were significant at the .01 level; r² was .370 in the experimental group and .296 in the control group, with "r = .608" in the experimental group.

"the results indicated positive linear relationships between the scores of the immediate vocabulary test and the reading comprehension test in the experimental group (r = .608, p = .001) and in the control group (r = .544, p = .002)."

Lin 2013 (2)¶

q2 · i3 · causal · r2

Correlational analysis of delayed vocabulary and reading comprehension scores. The article reports r² of .589 in the experimental group versus .352 in the control group, suggesting vocabulary scores predict reading comprehension more strongly after hierarchy exercises.

"The re sults revealed that they we re significantly correlated in the experimental group (r = .767, p = .000) and in the control group (r = .593, p = .001). The r value was higher in the experimental group than in the control group."
