Document Summary
Chapter 11: statistical association in contingency tables page #188-214: statistical association the relationship between two or more variables. It is called a contingency table under the assumption that the value on some variable is contingent upon the value on some other variable. ) a statistical test of independence between two categorical variables. The critical values of this test depend on the significance level (a) and the degrees of freedom. Under this condition, the pursuit of causal relations also acquires that we determine the nature and magnitude of the statistical association among variables. The size of this cross-tabulation of variables is based on the number of categories of the row variable and the number of categories of the column variable. Two types of marginal distributions involve the row frequencies and column frequencies. Two types of marginal distributions involve the row frequencies and column frequencies: joint distributions the intersection of any two categories of two variables in a contingency table.
