Correlation coefficient

My understanding is: two variables as they relate to one another and how accurately you can predict their behavior to one another when together.

Basically the strength of the linear association between two variables. When the variables have a tendency to go up and down together, this is a positive correlation coefficient. Variables with a tendency to go up and down in opposition, (one ends up with a high value and the other a low value) this is negatiove correlation coefficient.

An example would be the amount of weight a mom gains during pregnancy and the birth weight of the baby
