Question

Imagine you are creating a scatter plot to show the relationship between air temperature and electricity usage. As air temperature increases, so does electricity usage.
What type of trend would represent that correlation?

Answer 1

The type of trend that will represent the correlation will be a positive correlation.

What is correlation?

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.
