Subclaims¶

q2 i? On the delayed vocabulary post-test one week later, the hierarchy group (M = 83.04) significantly outperformed the copying group (M = 67.86), t(53.229) = 2.159, p = .035. → Lin 2013 (2) q2 i? Scores declined from immediate to delayed post-test in both groups, but the decline was smaller in the hierarchy group (5.77 points) than in the copying group (8.35 points). → Lin 2013 (2)

q2 · i? · causal · r1

Delayed vocabulary post-test administered one week after the immediate post-test, with no advance notice and no additional practice. Independent t-test showed the hierarchy group retained significantly more words than the copying group.

"The mean of the experimental group (M = 83.04, SD = 23.71) was higher than that of the control group (M= 67.86, SD = 28.80). The results revealed that there was a significant difference between the two groups ((t (53.229) = 2.159, p = .035< .05)."

q2 · i? · causal · r1

Descriptive comparison of immediate and delayed means in both groups. The article reports the between-test difference "in the experimental group (5.77) was less than that of the control group (8.35)", attributing decline to the one-week time lapse without rehearsal.

"In the experimental group, the mean scores decreased from 88.81 to 83.04 and in the control group the mean scores decreased from 76.21 to 67.86."
