Gabriel's method of assigning participants is a matched-pairs design. This design involves matching participants on a variable of interest and then randomly assigning them to different conditions of the experiment. This ensures that each condition has similar groups of participants, controlling for the variable of interest. It is useful when the variable of interest may confound the results or when within-group variability is expected to be high.
