Subclaims¶

q2 i? In the test of between-subjects effects, the pretest covariate was not a statistically significant predictor of posttest scores (F = .461, p = .499). → Nanteni Ganesan & Leong Kwan Eu 2018

q2 · i? · causal · r2

Row from the ANCOVA Tests of Between-Subjects Effects table (Table 6) for the same 72-student quasi-experiment. The pretest source shows F = .461 with Sig. = .499 and partial eta squared .007; no separate effect-size interpretation is given for this term.

Discussion¶

Learner Variables¶

• Prior Knowledge — predictor: learners who differ on it differ in outcomes
• Statistical Reasoning — predictor: learners who differ on it differ in outcomes

Related Claims¶

• Form Four students taught statistical reasoning with Fathom outperformed control-group students on posttest statistical reasoning scores after controlling for pretest — related
• Pretest scores significantly predicted posttest scores, supporting the pretest as an ANCOVA covariate in this study — reports the opposite
