Correlation is Positive when the values increase together, and ; Correlation is Negative when one value decreases as the other increases; A correlation is assumed to be linear (following a line).. 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 ...
