can a set with only one element have mean or median??
or is it a that the inherent definition of mean/ median is only for a set of nos.?
IMO,
why not..

in that case
mean=median=element itself.
standard deviation=0

Everyone is correct above- if a set contains only one element, x, then the median and mean are both x. The range and standard deviation are both zero.

And the following are also true:

0^0 is undefined
|0| = 0
