One can analyze the data separately for each order to see whether it had an effect. the chance of detecting a genuine effect of the independent variable.

The tailored participant-matching process reduces the risk of participant variables (individual differences) from affecting results between conditions. In a between-subjects design, people are only assigned to a single treatment.
