O testowaniu istotności współczynników korelacji cząstkowej i wielorakiej dla wielowymiarowych tablic wielodzielczych

The chi-square test of independence is used for data presented in contingency tables. The three dimensional contingency tables are analyzed in the paper. If the independence test leads to a significant result, then a researcher should conduct additional analysis to clarify the nature of the relationship between the three variables. The proposal of the partial independence test for data in contingency tables is presented in the paper. The proposal is based on the permutation test.
