Abstract :
It has previously been demonstrated that the median evoked response (MER) is appreciably less sensitive than the average evoked response (AER) to large artifactual disturbances [2]. It is shown here that for Gaussian noise, with artifactual noise absent, the confidence intervals of the median and average are comparable.
