q2 i? The two groups had the same level of pre-test achievement (p> .05), implying similar pre-knowledge of organic chemistry concepts. → Shariman and Talib 2017

Evidence¶

Shariman and Talib 2017¶

Tenku Putri Norishah Tenku Shariman and Othman Talib. (2017). OCRA, A Mobile Learning Prototype for Understanding Chemistry Concepts. 14th International Conference on Cognition and Exploratory Learning in Digital Age (CELDA 2017). https://www.worldcat.org/isbn/978-989-8533-68-5

q2 · i? · causal · r1

Between-group t-test on pre-test achievement (control mean 22.62, SD 7.79; experimental mean 27.86, SD 7.00; t value -3.43) in the quasi-experiment; the article reports no significant difference, and equivalence was not formally tested.

"Table 3 shows that the two groups have the same level of achievement (p> .05) even though the minimum score for the experimental group is higher than the minimum score for the control group although there is only a difference of five marks."
