True or false The correlation coefficient of 0.5 is stronger than a correlation coefficient of -0.8

What is the importance of correlation coefficient?

A correlation of r = – 0.95 is stronger than r = + 0.70. true or false?

What does a coefficient of correlation of 0.70 infer?

What is the relationship between covariance and the correlation coefficient?

Please give an example of an IMPOSSIBLE correlation coefficient.

What does a correlation coefficient of 2​ indicate? There is a weak relationship between the two quantitative variables.  It indicates a calculation​ error, as the correlation coefficient cannot be 2. There is a strong relationship between the two quantitative variables. It indicates a​ non-linear relationship between the two quantitative variables. There is no linear relationship between the two quantitative variables.

Explain correlation and its importance.

An ecologist is interested in exploring the relationship between pollination rate and the number of bees present at apple orchards. The relationship is: (Pollination rate) = 372.6 + 13.5 x (bees) with r = 0.80. The best interpretation of the correlation coefficient is: (pick one) 1. 64% of the variability in pollination rate observed at apple orchards is explained by the relationship with the number of bees 2. the correlation between pollination rate and number of bees is 0.64 3. 80% of the variability in number of bees at apple orchards is explained by the relationship with the pollination rate 4. the correlation between pollination rate and number of bees is 0.80

What are some of the possible reasons for large correlations betwen a pair of variables, X and Y?
