In the article discussing the chi-square test,1 I used a clinical trial scenario with the objective of assessing the clinical alignment efficiency of 2 types of wires. These wires (A and B) were used for 6 months in 2 patient groups, and the outcome recorded was binary: reaching complete alignment (success) or not reaching complete alignment (failure).

Many medical and epidemiologic studies incorporate an ordinal response variable. In some cases an ordinal response Y represents levels of a standard measurement scale such as severity of pain (none, mild, moderate, severe). In other cases, ordinal responses are constructed by specifying a hierarchy of separate endpoints.

Binary responses are commonly studied in many fields. Examples include 1 the presence or absence of a particular disease, death during surgery, or a consumer purchasing a product. Often one wishes to study how a set of predictor variables X is related to a dichotomous response variable Y.
