The strength of an association between variables is described by correlation, and it is typically captured by the correlation coefficient.
Its value ranges from-1 to +1. These are perfect positive and perfect negative correlations. Variables moving in the same direction are with positive correlation. And opposite moving variables are with negative correlation. All data points of a perfect correlation which ranges from -1 to +1, lie on a straight line.
