The method being used is matching, as participants are being assigned to conditions based on a specific characteristic (education level) to control for its potential influence on the outcome. Randomization involves randomly assigning participants to conditions without regard to specific characteristics. Holding constant involves keeping a variable constant across all participants, which is not the case in this study. Limiting the range involves only selecting participants within a certain range of a variable, which is also not the case in this study.
