In research writing, the term that indicates the logical relationship between two variables is called:

• A. Connotation
• B. Analysis
• C. Correlation
• D. Denotation

Answer: (C)

Correlation is the term used in research writing to describe the relationship between two variables. It shows whether and how strongly the variables move together: a positive correlation means both tend to increase together, while a negative correlation means one tends to increase as the other decreases. The strength of this relationship is often measured with a correlation coefficient, typically ranging from -1 to 1. Connotation and denotation are about word meaning, not data relationships, and analysis refers to the process of examining data rather than describing how variables relate. So, correlation is the standard way to express how two variables are related in studies, though it doesn't by itself prove causation.
