The weight of school grades: Evidence of biased teachers’ evaluations against overweight students in Germany
Fig 2
Teachers’ grading bias (measured in log-odds) according to students’ BMI.
The graph shows log-odds ratios from the 3-level hierarchical ordered logit model on mathematics grades (left) and German (right). Bars represent 95% confidence intervals. Model 1 adjusts for students’ competence level and socio-demographic variables, while model 2 also includes students’ psychological traits, and school-related attitudes and behavior. N = 3,754. Analysis conducted on 50 multiply imputed datasets.
