In biostatistics, we often have categorical variables, and the data is frequently represented by the fact that it belongs to certain categories. In biostatistics, chi-square is often used for categorical variables (data). One such example is whether the lipids belong to a category within the normal or abnormal reference range.

To understand this, let’s check the code where first, we will need to load the data and create a new column that will contain information about categories based on the reference threshold for the TG variable. Then, we can use that...
