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.
The correlation coefficient shows the strength and direction between the two variables.
The most common method of calculating correlation is Pearson product correlation. Pearson correlation measures the linear relationship between two variables.
