Question

which is the best estimate for the value of r in the scatter plot? variable y 10 9 8 7 6 5 4 3 2 1 0 variable x 0 1 2 3 4 5 6 7 8 9 10 -0.2 0.9

Explanation:

Step1: Analyze scatter - plot trend

The points in the scatter - plot show an upward trend, indicating a positive correlation.

Step2: Evaluate correlation strength

The points are closely clustered around an upward - sloping line, suggesting a strong positive correlation. The correlation coefficient $r$ ranges from - 1 to 1, where values close to 1 indicate a strong positive correlation, values close to - 1 indicate a strong negative correlation, and values close to 0 indicate a weak correlation.

Answer:

0.9
