Document Summary
A table is a simple n x n visualization of the includence of joint occurrence of particular values of each of the variables. The analysis of tables is a relatively simple, straightforward technique that allows us to assess the. Find the cell that indicates women on the left: bottom right are women on the right. 0 is left and 1 is right. Strength of relationship, keep in mind of the dimensionality and level of measurement of each of the variables. Depending on the dimensionality and level of measurement, we use different measures of association to assess strength. Different researchers prefer different measures of association. Case1: if we have two binary variables, use phi. Case 2: if we have a nominal variables, use cramer"sv. Case 3: if we have two symmetric ordinal variables, use tau-b. Case 4: if we have two asymmetric ordinal variables, use tau-c.
