Subclaims¶

q2 i2 The correlation between pretest and posttest was significant, r=0.21, p<0.05. → Mosley 2016

q2 · i2 · causal · r1

Correlational analysis of the study's own pretest and posttest administrations, used to justify ANCOVA: "the pretest was used as a single covariate in a simple ANCOVA analysis". The printed correlation is r=0.21, p<0.05.

"The correlation between the pretest and the posttest was significant (r=0.21, p<0.05)."

Discussion¶

Related Claims¶

• Pretest scores significantly predicted posttest scores, supporting the pretest as an ANCOVA covariate in this study — possibly the same claim (merge candidate)
• Pretest performance and average math grade correlate with conceptual knowledge but not procedural knowledge posttest scores — related
• GPA, pretest score, and self-generated elaboration jointly predict intellectual skills but not procedural knowledge or attitudes — related
