A data codebook is the collection of all data gathered by a particular data set.

• A. Data Codebook
• B. Theory
• C. RFP
• D. Hypothesis

Answer: (A)

A data codebook is metadata that describes a dataset—defining each variable, its meaning, how it’s coded, its measurement scale, and the rules for handling missing data. This guide helps you interpret and analyze the data correctly, but it isn’t the data itself. The actual collection of values across all records is the dataset, while the codebook explains what those values represent and how they were collected. The other terms don’t fit because a theory is an explanatory framework, an RFP is a procurement document, and a hypothesis is a testable proposition; none serve as the descriptive guide to a dataset’s structure outlined by a codebook.
