What does it mean if two variables have a strong negative correlation?

• A. They have a strong positive relationship.
• B. They tend to vary together in opposing directions.
• C. They fail to demonstrate any relationship.
• D. They indicate randomness without a pattern.

Answer: (B)

When two variables have a strong negative correlation, it means that as one variable increases, the other variable tends to decrease, and vice versa. This opposing relationship between the two variables signifies that they move in opposite directions consistently. In the context of correlation, this strong negative correlation indicates a predictable and inverse association. For example, if one were to analyze the relationship between the amount of time spent exercising and body weight, one might find that as exercise increases, body weight tends to decrease, illustrating a strong negative correlation. The other options do not accurately describe the nature of a strong negative correlation. A strong positive relationship implies that both variables move in the same direction, showing that this option is contrary to the defined characteristics of a negative correlation. Failing to demonstrate any relationship would indicate no correlation at all, which is not the case with a strong negative correlation. Lastly, indicating randomness without a pattern describes variables that are unrelated, which contradicts the concept of correlation where a clear inverse relationship is established.
