Which of the following steps is included in data consolidation?

• A. Normalize the data
• B. Handle missing values
• C. Access and collect the data
• D. Reduce the number of attributes

Answer: (C)

Data consolidation is a critical step in the data preparation process, where data from multiple sources is brought together into a unified format for analysis. Accessing and collecting the data is foundational to this process, as it involves identifying where the relevant data resides and extracting it for further processing. This step ensures that all necessary datasets are gathered, allowing for a comprehensive view of the information that will ultimately be analyzed. While other steps such as normalizing the data, handling missing values, and reducing the number of attributes are important components of data processing, they fall under data cleaning or transformation rather than data consolidation. Data consolidation primarily focuses on the integration of data sources before any specific processing techniques are applied. Understanding this distinction is crucial for effectively managing data in analytics projects.
