q2 · i? · causal · r2

Paired sample t-test on the 20-student experimental group taught through short stories; speaking pretest mean 12.80 rose to 17.22. The article reports the Sig. value (2-tailed) was less than 0.05, so "the null hypotheses ( H01 and H02) were rejected"; no effect size is printed.

"the mean difference of speaking achievement between pre-test and post -test in experimental group was 4.975 with the standard deviation was 1.3810"

Discussion¶

Related Claims¶

• The control group also made statistically significant pretest-to-posttest gains in speaking and writing, so improvement was not exclusive to the short-stories treatment — related
• Posttest speaking and writing achievement was significantly higher for students taught through short stories than for control-group students — related
