Correlation

The word Correlation is made of Co- (meaning "together"), and Relation
Correlation is Positive when the values increase together
Correlation is Negative when one value decreases as the other increases
A correlation is assumed to be linear (following a line).

Correlation Coefficient

Correlation can have a value:
1 is a perfect positive correlation
0 is no correlation (the values don't seem linked at all)
-1 is a perfect negative correlation
The value shows how good the correlation is (not how steep the line is), and if it is positive or negative.
