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 contingency table
tests employing a level of significance of p<0.
According with the first contingency table
, consumers who have bought counterfeits and know people into their environment that buy fakes represent 11,1% of the sample.
It is called a Contingency Table
, or Cross Tabulation.
Example 2: Consider the contingency table
(CT), in Table I, for the customer preference to buy tea or coffee.
The first step in this approach is to build the contingency table
which basically is the matrix format representation of the original table.
Loglinear analysis is an extension of the two-way contingency table
where the conditional relationship between two or more discrete, categorical variables is analyzed by taking the natural logarithm of the cell frequencies within a contingency table
