We broke down the dataset in a series of 2x2
contingency tables like the one presented in Figure 1.

j] have the same interpretations as in the 2x2
contingency table (above) but the range of the scale is extended to i,j=1, .
When using correspondence analysis approach, a
contingency table of frequencies is usually standardized firstly.
These approaches solely depend on the information contained in 2 x 2
contingency table.
The analyses for this report consisted of chi-square

According with the first
