q2 · i? · causal · r1

Pretest-posttest quasi-experimental control group study; 50 students taught by demonstration and 50 by lecture for three weeks. Post-test means were 54.06 (experimental) and 52.80 (control); the article reports "experimental group had higher score than the control group" and rejected Ho1.

"The result obtained from both t-tests and ANOVA tes ts show that there is significance difference between the two group's in terms of their learning outcome in the post test. This means experimental group had higher score than the control group"
