B. Data Transformation
Data transformation is a very crucial process in data preprocessing.
It involves normalization and aggregation.
Normalization is a process of scaling the value of data to
specific rate. Normalization can be done using the min-max or
the z-score methodology. For this study, the min-max
normalization technique is used to normalize the dataset. As a
principle, the min-max normalization result always ranges
between 0 and 1.
C. Data Set Split
The pre-processed dataset was split into two halves of
varying sizes at different times for use as training and testing
data set across the different data mining classification
