Notes and Considerations

Chi-Squared analysis of crosstab table with 2 rows and 2 columns 
 
This example incorporates two methods of analyzing the data.
1.  Chi-square analysis using the cross-tab method and Pearson's chi-square test statistic.
2.  Generalized Linear Modeling using the (M-L) Maximum Likelihood chi-square test statistic. 
 
This example also includes an example of calculating and interpreting the Odds Ratio and its interval estimate.
