q2 · i? · causal · r2

Quasi-experimental study of 80 English-major students randomly assigned to experimental (n=40) and control (n=40) groups; independent-samples t-test on post-test essay scores. The experimental mean was 47.56 (SD 2.74) versus 35.32 for the control, and "this difference between the post- test means scores was significant as t value was 23.24 with degree of freedom (78)".

"the post test mean scores of student’s writing performance for the experimental group that was taught using brainstorming strategy was (47.56) with standard deviation (2 ,74) while the mean scores of the students’ writing performance for the control group taught traditionally was 35.32"
