WebApproach #2 - Label Encoding. Another approach to encoding categorical values is to use a technique called label encoding. Label encoding is simply converting each value in a column to a number. For example, the body_style column contains 5 different values. We could choose to encode it like this: convertible -> 0. WebJan 30, 2024 · Using the Chi-square test, we can estimate the level of correlation i.e. association between the categorical variables of the dataset.
