What is the coefficient of correlation given this data: X = 51, 42, 34, 10, -1 Y = 59, 30, 24, 19, -11 Please format to 2 decimal places.

The correlation coefficient ranges from which two values?

How is correlation defined?

is finding a linear correlation coefficient the same as finding the correlation coefficient? if not, an example of linear correlation coefficient would help.

True or False: If the correlation coefficient from two variables X and Y , the number of shark attacks and number of iced lemonade sales, respectively, is r= 0.98, we can conclude that an increase in iced lemonade sales causes an increase in shark attacks.

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.

if the slope is negative then is the correlation coefficient also negative?

Explain correlation and its importance.

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