A statistical method is presented whereby the information provided by a small number of nuclear scatters of LAMBDA deg decay protons can be used to determine the sign of the asymmetry parameter due to parity nonconservation in LAMBDA deg decay. The analysis is applied to twenty-one proton scatters of LAMBDA deg hyperons decaying in the Princeton multiplate cloud chamber. Because the asymmetry to be expected in each observed nuclear scatter is small, the data do not yield a statistically significant result. However, if each experimenter wouhd follow a similar proceduree with his data, it should be possible to combine results to determine the sign with a high degree of certainty. (auth)
