q2 i? On paired item-level t-tests, the experimental group showed significant pre-post gains on items E and F where the control group's posttest was similar to its pretest, while the control group gained significantly on items A and C where the experimental group did not. → Carolina Salamanca & Sara I Montoya 2018

q2 · i? · causal · r1

Paired-samples statistics by item (Table 7): experimental item E t -3.024 sig .005 and item F t -2.953 sig .006, versus control item E sig .580 and item F sig .769. The article adds that for items A and C the control group gained significantly while the experimental group was similar to its pretest.

"For the experimental group, the mean of the posttest is significantly higher than the mean of the pretest in the items E and F, while for the control group, the average of the posttest is similar to the pretest."
