Meta data is what how and why of data

There are 5 Data Preprocessing Steps:
1: Data Cleaning (tiding-up the data, discarding unnecessary data, Imputing missing values)
2: Data Integration/Pooling (use triangulation method for verifying the data validity, it causes data redundancy but we can remove duplicates, NO WORRIES)
3: Data Transformation (Scaling, Normalization, Aggregation, Data Generalization -->make groups of data so we can fit the model, binning is used)
4: Data Reduction (Dimensionality Reduction--> PCA, Multivariate Analysis, Numerosity Reduction--> Converting Categorical to Numerical {0,1}, Data Encoding, Data Compression)
5: Data Discretization ( Converting Numerical variables--> Nominal(Categorical) binning techniques are used)
