A non stationary state in the one-dimensional infinite square well formed by a combination of the ground state and the first excited one is considered. The statistical complexity and the Fisher-Shannon entropy in position and momentum are calculated with time for this system. These measures are compared with the Heisenberg uncertainty relation, $\Delta x\Delta p$. It is observed that the extreme values of $\Delta x\Delta p$ coincide in time with extreme values of the other two statistical magnitudes.
