In a study of two variables, when one variable goes up as the other goes down in value, it is known as a
APositive correlation
BNo correlation
CNegative correlation ✓ Correct
DFluctuating correlation
Correct answer: (C) Negative correlation — When one variable rises as the other falls, it is a negative correlation, so that is the answer.
Explanation
★When one variable rises as the other falls, it is a negative correlation, so that is the answer.
★A negative correlation means the two variables move in opposite directions.
★So as one increases the other decreases, which is exactly the pattern described.
★A positive correlation would have both variables rise and fall together.
★No correlation means the variables show no consistent relationship at all.
★There is no standard 'fluctuating correlation' category, so opposite movement is a negative correlation.
