Question
![The image presents a set of six scatter plots labeled (A) through (F). It poses the question: "In which scatter plot is r = 0.3?" Here, "r" refers to the correlation coefficient, a measure of the strength and direction of a linear relationship between two variables.
- Scatter Plot (A): Data points with a slight downward trend.
- Scatter Plot (B): Data points with a slight upward trend, more linear than (A).
- Scatter Plot (C): Data points scattered widely with no apparent trend.
- Scatter Plot (D): Data points tightly clustered with a strong downward trend.
- Scatter Plot (E): Data points widely scattered, showing a weak positive trend.
- Scatter Plot (F): Data points moderately scattered with a downward trend.
A note at the bottom asks: "The graph [ ] shows a scatter plot with a correlation coefficient of r = 0.3. (Type A, B, C, D, E, or F.)" indicating that one of these graphs corresponds to an r value of 0.3, typically indicating a weak positive linear relationship.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F58402a47-f1ff-47ea-9009-84135bb68162%2Ff310c357-b895-4fd2-97a5-a177874f62a7%2F2hjwvb8_processed.jpeg&w=3840&q=75)
