Answer: correlation vs. causation
Explanation:
Correlation assesses the relationship between variables and can be in the same direction, where the increase in one exists as the same time as an increase in the other variable or inverse where an increase in one variable occurs when there is a decrease in the second variable. However, this correlation does not indicate causation.
Causation signifies that one variable is responsible for the occurrence of an event in the other variable.
