The Monte Carlo method was used to calculate the relative dispersions of the magnetization R_m, susceptibility R_χ, and heat capacity R_C for a weakly diluted impurity Potts model with the number of spin states q = 4. It is shown that the introduction of disorder in the form of nonmagnetic impurities into the two-dimensional Potts model with q = 4 on square lattice leads to nonzero values for R_m, R_χ, and R_C at the critical point.
