  1. This table presents descriptive statistics for the variables used. The scales of these variables were defined in Table 1. First, the number of participating students on each variable is presented, then minimum and maximum values followed by mean and standard deviation are provided. Cronbach’s alpha presents the internal consistency of the scale variables
  2. aWarm’s Mean Weighted Likelihood Estimates (WLE) are computed for the PISA indices used in our study. These values are drawn from the PISA data repository. The WLE estimates are standardized across OECD countries and have a mean of zero and standard deviation of one
