q2 i? There was no statistically significant difference between the experimental group (M=48.86, SD=18.38) and the control group (M=49.14, SD=17.70) on the grammar posttest (p=.951). → Karaazmak 2018

q2 · i? · causal · r1

Independent samples t-test comparing posttest scores of the experimental group (n=29) and control group (n=35) in a quasi-experimental study of 64 eleventh-grade students. The article reports "No significant difference ( p.951>.05)"; equivalence was not tested.

"No significant difference ( p.951>.05) was detected between the results of the post -test concerning the experimental ( M=48.86, SD=18.38) and the control group (M=49.14, SD=17.70) as reported in table 1."

• The authors interpret the experimental group's score increase as larger than the control group's, suggesting a possible but unsatisfied effect of error correction — related
