Interval data has very distinctive attributes that make it distinct in comparison to nominal data, ordinal data or even ratio data. Interval data doesn’t have a defined absolute zero point which is present in ratio data. The lack of absolute point zero makes comparisons of direct magnitudes impossible. For example, Object A is twice as large. Transformasi data ordinal menjadi interval itu, selain merupakan suatu kelaziman, juga untuk mengubah data agar memiliki sebaran normal.
