Abstract
We simulated site dilute Ising models in dimensions for several lattice sizes . For each singular thermodynamic quantities were measured at criticality and their distributions were determined for ensembles of several thousand random samples. For the relative width of tends to a universal constant: there is no self-averaging. The width of the distribution of the sample dependent pseudocritical temperatures scales as and not as . The sample dependence of enters dominantly, but not exclusively, via .
