We present a graphical and statistical comparison of observations of solar neutrinos with theoretical predictions for the Mikheyev-Smirnov-Wolfenstein effect and a class of «nonstandard» solar «models.» The method used to compare the results makes the level of agreement or nonagreement between theory and observation more readily apparent. Included in our analysis are the standard-solar-model flux uncertainties. We also present predictions for Solar Neutrino Observatory charged-current rates
