11. Correlation

Given a scatterplot showing a strong negative linear relationship between two variables, which of the following is most likely the correlation coefficient for the data set?

Based on the scatterplot, select the most likely value of the linear correlation coefficient $r$.

Correlation means all of the following except that $\_\_\_\_\_\_$.

Which value of the Pearson correlation coefficient $r$ provides the strongest evidence that there is a linear correlation between the data?

The correlation coefficient $r$ is a measure of the extent to which two factors:

Which $r$-value represents the strongest negative correlation?

Which of the following is not measured or described by a $r$ (correlation coefficient)?

Which of the following statements about the correlation coefficient is true?

Given a scatterplot showing a strong negative linear relationship between two variables, which of the following is most likely the correlation coefficient for the data set?

Which of the following is a measure of how well the regression fits the sample data?

Which of the following statements is true about the correlation coefficient?

Given a dataset where the variables have a strong negative linear relationship, which of the following values is most likely to be the correlation coefficient?
