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

Answer: (B)

A testable statement about the relationship between variables is a hypothesis. In research, a hypothesis makes a specific prediction about how two or more variables relate and is phrased so that evidence from data can support or refute it. It can be directional (predicting the expected direction of the relationship) or non-directional, but it must be testable through measurement and analysis. A theory, in contrast, is a broader, well-supported explanation that ties together many observations and hypotheses. A data codebook is a documentation of how data are coded, including variable names, values, and meanings. An RFP is a request for proposal, a document used in procurement, not in research.
