What is Data Manipulation?

• A. Transforming data into visual graphs only
• B. Storing data in databases
• C. Task of transforming, summarizing or modeling data to support decision making
• D. Transformation of data to make it easier to read

Answer: (D)

Data manipulation means changing data so it can be used more easily. This includes adjusting format, cleaning, organizing, and presenting data in a way that makes it readable and interpretable. The choice describing transforming data to make it easier to read fits this idea best, since readability is a core part of making data usable. Other options describe storage, visualization, or broader analytical tasks, which go beyond the manipulation step itself.
