E. Martz tells us that chi-square analysis can be used for more than just practical applications:

Chi-square analysis compares the counts of two categorical variables to tell you if a relationship exists between the variables or not. You can apply chi-square analysis to answer important questions about factors in everyday life, and even about events like elections... or Halloween. If you are a character in a slasher film, is there a connection between your gender and your dying in some horrible manner?

As explained in the above passage, you can use chi-square analysis to compare a wide range of topics.
