the product of a negative and a positive which is negative. In the formula for r these are added up. If you add up numbers that tend to be negative you will get a negative. r is always between -1 and 1(not obvious, but can be proven). r near 0 indicates a very weak linear relationship. As r moves away from 0 the linear relationship is stronger.

The Correlation Matrix helps you to identify symbols with strong or weak correlation. 2. Using the Correlation Matrix. 2.1 The matrix. The Correlation Matrix shows the correlation between a grid of selected symbols. For example: Each cell in the matrix is color-coded: Green. No correlation (0 to ± 25) Blue. Weak correlation. (±25 to ±50) Orange.
