Easy Statistics question ?

Is it possible to find an example of a statistic that does not estimate any corresponding population parameter? I can't think of one.

You can use any statistic (function of data) to estimate any parameter. The question is whether the statistic is a "good" estimator for the parameter.I could use min(x1, x2, .......xN) to estimate the mean, but that would be a very poor estimator.
