The closest correlation coefficient (r-value) for these data is -0.3.
Given
Ben wanted to know if there was a correlation between the height of a dog and its age.
He collected data and created the scatterplot shown.
Correlation Coefficient;
The correlation coefficient is a measure of the mutual relationship between two variables.
The correlation coefficient, r, ranges from 1 to -0.3.
On a scatter plot, if the data points are clustered along the line of best-fit, the correlation coefficient is strong and away from 0, and vice versa, also it is negative if the line of best-fit or trend slopes upwards from left to right, and vice versa.
The scatterplot when the data points are clustered together, it means the correlation is strong. But when it is scattered, it means that the correlation is weak and not very strong.
It also shows that there is a negative relationship between the variables since they are going from left to right.
Hence, the closest correlation coefficient (r-value) for these data is -0.3.
