If there is no correlation, r2 is equal to zero. Correlation coefficient, r, the square root of r2--positive or negative, depending on. the type of correlation--range -1 to +1. Note: ρ (rho) and ρ2 are the population parameters corresponding to r and r2. Correlation and causation. The presence of correlation does not, in itself, prove that x ...

Due to chance factors, two variables that are in fact unrelated in nature, are unlikely to yield a perfect-zero correlation coefficient when we measure any specific group of 50 people (just like a perfectly balanced coin is unlikely to yield exactly 25 heads in 50 tosses). So, the question becomes: how high does a correlation coefficient ...

Correlation coefficient measures only linear (straight-line) relationships between two variables. More complicated types of relationships (such as curvilinear ones) can go undetected by r. Thus, there might be a relationship, albeit not a linear one, even if the correlation is close to zero.
