Hypothesis: A hypothesis is a tentative and testable statement about the relationship between two or more variables, which can be either supported or refuted through scientific research.

Identify the correct term for a tentative prediction about the relationship between two variables

Now that you have an understanding of the provided terms, it's time to identify which one fits the description of a tentative prediction about the relationship between two variables. As a hypothesis is a tentative and testable statement about the relationship between two or more variables, it is the correct answer. So the answer for this exercise is: D. a hypothesis.
