Note: Bolded coefficients indicate a significance level of at least p < 0.05. Frequencies rounded to the nearest 10 per NŒS guidelines. Balance is achieved when mean values between labeled and unlabeled students within a stratum are not statistically significant at at least a 0.05 confidence level. The column titled 'Balance' shows the percentage of covariates that are balanced within each stratum.
