What is the relationship expressed by a negative correlation?

• A. The variables are unrelated to each other.
• B. As one variable increases, the other also increases.
• C. As one variable increases, the other tends to decrease.
• D. The variables fluctuate independently.

Answer: (C)

A negative correlation indicates that there is an inverse relationship between two variables. This means that when one variable increases, the other variable tends to decrease. For instance, if you consider the relationship between the amount of time spent studying and the number of errors made on a test, you might find that as study time increases, the number of errors tends to decrease. This reflects a negative correlation. The other options do not align with the definition of a negative correlation. Unrelated variables would not show any systematic relationship at all, while a positive correlation implies that both variables move in the same direction. Lastly, independent fluctuations would suggest no discernible pattern, which is not indicative of a correlation, whether positive or negative. Thus, the understanding of how one variable’s increase corresponds to the other’s decrease is crucial in recognizing a negative correlation.
