1. If you can predict y from x with 100% accuracy, you can refer to this as a perfect relationship.
2. As one variable goes down, the other goes down. This describes a positive relationship.
3. The covariance formula differs from the variance formula in that instead of squaring the difference between each score and its mean, we multiply the difference between each x score and its mean with each y score and its mean.

5. A correlation can be calculated by adding each multiplied pair of z-scores together and dividing by degrees of freedom.
