The correct answer to fill in the blank is "Correlation."

Correlation is a statistical measure that describes the degree to which two variables move in relation to each other. When researchers analyze data, they often look for correlations to understand how variables interact. A positive correlation indicates that as one variable increases, the other variable also tends to increase, while a negative correlation indicates that as one variable increases, the other tends to decrease. Correlation does not imply causation, meaning that just because two variables are correlated, it does not mean that one causes the other to change. Understanding correlation is fundamental in fields like economics, psychology, and environmental science, where multiple variables often influence outcomes.
