<h3>What is correlation?</h3>
Correlation is a statistical model that is used to determine the kind of relation, if any, that exists between two variables.
The correlation coefficient, denote by r, is a variable that measures this relationship.
The correlation coefficient could take up a value between +1 and -1. A positive value of r means that both variable moves in the same direction. A negative correlation means they are moving in opposite directions.
Perfect correlation is denoted by +1 or -1.
Thus, if air temperature increases along with electricity usage, it means the two variables are positively correlated.
