Step 3: Splitting the dataset into the Training set and Test set. Similar to the Decision Tree Regression Model, we will split the data set, we use test_size=0.05 which means that 5% of 500 data rows ( 25 rows) will only be used as test set and the remaining 475 rows will be used as training set for building the Random Forest Regression Model.
