Bias in grading: A meta-analysis of experimental research findings
Abstract
This article provides a meta-analysis of experimental research findings on the existence of bias in subjective grading of student work such as essay writing. Twenty-three analyses, from 20 studies, with a total of 1935 graders, met the inclusion criteria for the meta-analysis. All studies involved graders being exposed to a specific type of information about a student other than the student’s performance on a task. The hypothesized biasing characteristics included different race/ethnic backgrounds, education-related deficiencies, physical unattractiveness and poor quality of prior performance. The statistically significant overall between-groups effect size was g = 0.36. Moderator analyses showed no significant difference in effect size related to whether the work graded was from a primary school student or a university student. No one type of biasing characteristic showed a significantly higher effect size than other types. The results suggest that bias can occur in subjective grading when graders are aware of irrelevant information about the students.

“Finally, assessment is indivisible from individual value judgements. No matter the structures and processes put in place, assessments are designed and evaluated by humans, with all their complex socio-cultural backgrounds, educational experiences, and intellectual and personal values (Malouff and Thorsteinsson 2016; Ryan and Viete 2009; Leathwood 2005; Stowell 2004).”

“Indeed, this was found to be a significant factor in student attainment outcomes when identity markers differed from those of academic staff (Malouff and Thorsteinsson 2016).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
