### Linear Correlation Coefficient / Pearson

The correlation coefficient is a statistical measure that indicates how a change in the
value of one variable affects the other.

When the value of a variable changes in the same direction as the other, we say that there is a positive correlation or positive correlation coefficient.
On the contrary the correlation is negative. However, when a variable increases or decreases in value, at random, the correlation is null or does not
exist.

The correlation coefficient ranges from -1 to +1 and the closer to the ends, more strong, the correlation.
