Coarsened data meaning
WebMay 22, 2024 · Reardon et al. (2024) described how heteroskedastic ordered probit (HETOP) models can be used to estimate the underlying means and standard deviations of the test score distributions based on coarsened test score data via maximum likelihood (ML), thus overcoming some limitations of the coarsening. In addition, because HETOP … Webdisattenuating standardized mean differences like 𝑑, then we extend this review to methods for disattenuating 𝑉 in full and coarsened data scenarios. We test the robustness of a simple disattenuation approach that requires only the reported reliabilities of the test, rather than raw or item-level data.
