Question

select the correct answer.

what is the approximate value of the correlation coefficient for the given graph?

1
5
3
-1

Explanation:

Analyze the slope of the line

The line on the graph slopes downward from left to right, which indicates a negative relationship between the number of years and the price of the car.

Determine the strength of the correlation

The data points (represented by the line itself or a perfect linear trend shown) form a perfect straight line with no scatter or deviation. This represents a perfect linear relationship.

Identify the correlation coefficient value

A perfect negative linear relationship has a correlation coefficient of exactly \(-1\).

Answer:

• (A) 1
• (B) 5
• (C) 3
• (D) -1 (Correct answer)
