q2 · i? · causal · r1

The pretest was the students' mid-term English exam with a total of 150 marks, used to check the rough equality of the two intact classes before treatment. The article reports the groups were "not significantly different (t=1.910, p=.064>.05)".

"the mean score of SR group (m=137.1579, std=5.38788) and the mean score of SU group (m=133.8947, std=5.14128) are not significantly different (t=1.910, p=.064>.05)."
