Although the Gastwirth median is fairly robust (resistant to effects of contamination), it does not, as far as is known, have appropriate confidence limits. It was suspected that it would have confidence limits similar to those of the median. This was borne out in this investigation, which was confined to symmetrical distributions. It is concluded that, for practical purposes, in approximately symmetrical distributions the confidence limits for the median can be assumed to approximate those for the Gastwirth median.
