Subclaims

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? The article argues that apparently positive school-average achievement effects on subsequent achievement can reflect failure to control measurement error and preexisting differences, citing Harker and Tymms (2004) and recent doubly-latent studies. → Marsh 2023

q2 · i? · associational · r3

Narrative review section attributing this argument to Harker and Tymms (2004) and recent doubly-latent studies (e.g., Dicke et al., 2018; Becker et al., 2022). The article defines "phantom effects" as positive bias due to uncontrolled measurement error and preexisting differences.

"Here, we use the term phantom effects to represent the positive bias in apparently positive effects of school-average achievement that are actually due to the failure to control for measurement error and preexisting differences."
