DOI: 10.1007/s10649-021-10067-8
Abstract: Past studies have documented some pre-service teachers’ (PSTs) difficulties in reasoning about sampling variability. This study adds to the body of literature by investigating the ideas that PSTs employ in reasoning about sampling variability, and… read more here.

DOI: 10.1029/2019gl082250
Abstract: We assess seasonal mean relationships between the El Niño–Southern Oscillation (ENSO) and surface fine particulate matter (PM2.5) over the United States using observations from 1999 to 2015. Through a case study of the springtime PM2.5… read more here.

DOI: 10.1103/physreve.105.064114
Abstract: We study statistics of data ranking, focusing on the recently discovered distribution-invariant discrete eigenvalue spectrum for an independent and identically distributed (IID) process. We employ a variant of a cumulative distribution function in rank and… read more here.

DOI: 10.1177/01466216221084215
Abstract: Assessing multidimensionality of a scale or test is a staple of educational and psychological measurement. One approach to evaluate approximate unidimensionality is to fit a bifactor model where the subfactors are determined by substantive theory… read more here.

Characterizing Sampling Variability for Item Response Theory Scale Scores in a Fixed-Parameter Calibrated Projection Design

DOI: 10.1177/01466216221108136
Abstract: A common practice of linking uses estimated item parameters to calculate projected scores. This procedure fails to account for the carry-over sampling variability. Neglecting sampling variability could consequently lead to understated uncertainty for Item Response… read more here.
