Data Preprocessing

As a mandatory step in our analysis, we must preprocess our data. Data preprocessing is the process of cleaning, transforming, and organizing the data to make it more suitable for analysis and modeling. This typically involves several steps, such as the following:

removing missing or duplicate values;
correcting inconsistencies;
transforming the data into a format that is easier to manage.
