Explanation / Answer

Relationship between variables

Evaluating the relationship between two variables, it is important to determine how the variables are related. Linear relationships are most common, but variables can also have a nonlinear or monotonic relationship. It is also possible that there is no relationship between the variables.

Linear relationship

A linear relationship is a trend in the data that can be modeled by a straight line.

When both variables increase or decrease concurrently and at a constant rate, a positive linear relationship exists.

When one variable increases while the other variable decreases, a negative linear relationship exists.
