Step 1:I'll solve this step by step, focusing on the concept of negative correlation.
Step 2:: Understanding Correlation
A correlation describes the relationship between two variables. In a negative correlation, as one variable increases, the other variable decreases.
Step 3:: Analyzing the Options
- As exercise time $$\uparrow$$ (increases), depression $$\downarrow$$ (decreases)
Let's examine each option carefully: A. "Students' shoe sizes are not related to their grades" - This describes NO correlation (neither positive nor negative) - Not a negative correlation B. "Students with lower IQ scores tend to have lower grades" - This suggests a positive correlation (lower IQ → lower grades) - NOT a negative correlation C. "As hours studying for a test decrease, so do grades on that test" - This is a CLASSIC example of negative correlation - Represents an inverse relationship D. "People who spend more time exercising tend to experience less depression" - This suggests a negative correlation between exercise time and depression
Step 4:: Identifying the Correct Answer
The clearest example of negative correlation is option C.
Final Answer
As hours studying for a test decrease, so do grades on that test.
