Definition
Data Preparation is the process of transforming, organising and adapting data to the requirements of analysis, reporting or modelling.
Human Explanation
Before analysis begins, data need to be appropriately organised and prepared for further use.
Why it Matters
Analysts often spend more time preparing data than performing the analysis itself.
Conceptual Boundary
Data Preparation does not include interpreting results. It ends when the data are ready for their intended use.
Practical Perspective
Data Preparation may include combining, filtering, aggregating, restructuring, standardising and cleaning data.
