  It has recently been argued that among the various suggested measures of
tripartite entanglement, the two particular measures, viz. the Concurrence Fill
and the Genuine Multipartite Concurrence are the only 'genuine' tripartite
entanglement measures based on certain suitably specified criteria. In this
context, we show that these two genuine tripartite entanglement measures can be
empirically determined for the two important classes of tripartite entangled
states, viz. the generalized GHZ and the generalized W states using the derived
relationships of these two measures with the observable statistical correlators
like the Pearson correlator and mutual information. Such a formulated scheme
would therefore provide for the first time the means to exactly quantify
tripartite entanglement, crucial for the proper assessment of its efficacy as
resource. We also point out two specific applications of this scheme, viz. a)
Enabling empirical demonstration of the potentially significant feature of
inequivalence between Concurrence Fill and Genuine Multipartite Concurrence in
quantitatively assessing which of the two given tripartite states is more
entangled than the other one. b) Enabling experimental detection of the
recently predicted phenomenon of entanglement sudden death for a tripartite
system.
