The confounding variables that will be controlled during the experiment are the following.
Subject’s technical skills To control the variability caused by each subject on their partner, pairs are kept the same during the entire experiment, although the subjects are not informed about this fact until the end of the experiment. Ideally, this would make the conditions of the two in–pair tasks the same except for the programming exercises (see below) and for the perceived gender in the case of the experimental group.
Programming exercises In order to avoid potential differences among the programming exercises used during in–pair tasks, they are of similar difficulty and are randomly assigned.
