The correct answer is: When one variable increases, the other decreases.
To determine the correct answer, we need to understand the concept of correlation. Correlation refers to the relationship between two variables and how they change together.
To find out whether variables are correlated, we can plot the data points on a scatter plot and observe the pattern. In this case, negative correlation is indicated by the first option: "When one variable increases, the other decreases."
Therefore, the correct answer to the question is: When one variable increases, the other decreases.
