Verified step by step guidance

1. Understand that the median of a data set is the middle value when the data are arranged in order.
2. Since the data set contains only one value, which is 0, there is no need to arrange the data because it already consists of a single element.
3. Recall that when there is only one number in the data set, that number itself is the median.
4. Therefore, identify the median as the single value present, which is 0.
5. Conclude that the median of the data set containing only the value 0 is 0.
