Why is it most appropriate to compute a chi-square when comparing frequency of gender (male/female) and smoking status (smoker/nonsmoker)?
 
  1. Gender and smoking status are both nominal-level variables in this example, and a chi-square requires nominal-level data.
  2. Gender and smoking status, as defined in this case, are both ordinal-level data, and a chi-square requires ordinal-level data.
  3. Chi-square is used in any research question where the independent variable is grouped according to gender.
  4. An ANOVA is the most commonly used test with nominal/nominal-level data.
