Answer 1

What does it mean if there is a correlation between X and Y?

The correlation of X and Y is the normalized covariance: Corr(X,Y) = Cov(X,Y) / σXσY . ... Correlation is a measure of the strength of the linear relationship between two variables. Strength refers to how linear the relationship is, not to the slope of the relationship.
