**Regression analysis** is a statistical method for examining the relationships between a dependent variable and one or more independent variables. Regression calculates the amount of change in the dependent variable when the independent variable moves one unit.
It aims to prove the relationship statistically.

To do that, regression analysis tries to formulate the relationship between the variables as much as possible
by using a linear line which is called the **regression line**.

For example, the chart below shows the locations of the data points across the axes. Can we claim that there is a relationship between the variables?
