How to write a correlation hypothesis. The correlation coefficient r measures the direction and strength of a linear relationship. A correlation reflects the strength and/or direction of the relationship between two (or more) variables. A correlation indicates that as the value of one variable increases, the other tends to change in a specific direction:

The question should be focused, specific, and researchable. Explore the art of interpreting correlation hypotheses with these illustrative examples. However, correlation must be exercised cautiously;.
