Which process involves changing data for better organization?

1. Data replication

2. Data transfer

3. Data manipulation

4. Random sampling

The correct answer is: Data manipulation

The process that involves changing data for better organization is data manipulation. This term refers to the techniques used to modify, organize, or process data to make it more useful or easier to analyze. Data manipulation can include tasks such as sorting, filtering, merging, aggregating, and transforming data. The goal is to prepare the data in a way that enhances its value and aids in deriving insights or making decisions. While data replication involves creating copies of data to ensure availability and redundancy, and data transfer refers to moving data from one location to another, neither directly changes the data's structure or organization. Random sampling is a technique used to select a subset of data from a larger dataset but does not involve changing data for better organization. Thus, the focus on enhancing the data’s utility qualifies data manipulation as the correct choice.
