# Data Split (DP\_4)

This process of separating data into two sets is a crucial step in the process of developing and evaluating machine learning models. It ensures that the model is able to generalize well to new, unseen data, and it also allows for a more accurate assessment of the model's performance.

This functionality of splitting data into training and test sets is widely used in the field of machine learning and data science.

## Sample Request

This request uses the mean strategy to fill in missing values in the second column to the end with the mean values of the X variable.
