What’s A Regression Test?
The Regression Test is a hypothesis test that determines whether there is a correlation between two paired sets of continuous data. It is useful for determining if changes in Y can be attributable to a particular X.

An example would be to test if rainfall and crop yield were correlated and then to calculate approximately how much water is required to achieve the desired yield.
