Question

Which of the following graphs shows a negative linear relationship with a correlation coefficient, r, close to -0.5?A. Graph AB. Graph BC. Graph CD. Graph D

Answer 1

A negative linear relationship occurs when for increasing x values, the values of y are decreasing.

Observing the graphs, we can see a positive linear relationship for graphs A and C (x - increases, y - increases).

For Graph D, we can observe no correlation.

For graph B, we can observe a negative linear relationship (x - increases, y - decreases).

Answer: Graph B
