  The neutrino mixing parameters are presented in a number of different ways by
the various experiments, e.g. SuperKamiokande, K2K, SNO, KamLAND and Chooz and
also by the Particle Data Group. In this paper, we argue that presenting the
data in terms of $\sin^2 \theta$, where $\theta$ is the mixing angle
appropriate for a given experiment has a direct physical interpretation. For
current atmospheric, solar and reactor neutrino experiments, the $\sin^2
\theta$'s are effectively the probability of finding a given flavor in a
particular neutrino mass eigenstate. The given flavor and particular mass
eigenstate varies from experiment to experiment, however, the use of $\sin^2
\theta$ provides a unified picture of all the data. Using this unified picture
we present a graphical way to represent these neutrino mixing parameters which
includes the uncertainties. All of this is performed in the context of the
present experimental status of three neutrino oscillations.
