We have collected times of minimum light available in the literature for WZ Andromedae and analyzed the nature of the period variations. The O-C diagram of WZ And clearly shows that two abrupt changes near JD 2418000 and JD 2435000 are deduced by dp/p = +4.24*10E-6 and dp/p = -2.46*10E-6, respectively. For these period changes, we have introduced the equations which represent mass exchange in the close binary systems give by Biermann and Hall(1973), and the computation yielded a mass flow of 7.42*10E-6 Mo from the hotter component to the cooler one. Due to the amount of mass flow, the period decrease may also be calculated. The theoretical new period after JD 2435000 became 0.69565858 days, which is in good agreement with the value 0.69566034 days found in the O-C diagram. In this computation, the mass ratio of WZ And suggested that the hotter star is the filling its Rochclooe, and thus WZ And is in Pacynski's stage II.
