The probability of a real fact

Any statistical observational unit is probabilistic. The probability of such a unit has to be computed on the basis of homogeneous data if we do not want to violate the basic principle of the calculus of probability. The model of the homogeneous representativeness can be employed to test data for homogeneity

The new statistical thinking

homogeneity, induction and deduction reasonings, statistical science, statistical axioms,

The sample estimation

Random factor, disturbance factor, homogeneity, population, quality control,

The new approach in the analysis of 2×2 tables

contingency tables, the null hypothesis of independence, cause and effect representativeness, the prior homogeneous population, the hypothesis of significant dependence,
