Partial Correlation - Assignment Example

The statistics try to establish a relationship that exists between the bodyweight of the driver and the gas mileage. However, wind resistance may be a third variable affecting the relationship between the body weight of the driver and the gas mileage. In some way, it means that wind resistance may increase the bodyweight hence it acts as an aircraft in this relationship. The only way one can solve such a problem is by calculation the correlation that partially exists between the bodyweight of the driver and the gas mileage with a resistance of wind being omitted in both variables.

The correlation existing between two variables bodyweight of the driver and the gas mileage with the resistance of wind or more partial variables omitted on the two variables. It is a correlation that exists between the bodyweight of the driver and the gas mileage that is residualized on the third variable which is the resistance of the wind. This partial correlation research is of more significance as it provides one with a chance to establish the statistics that exist in more than two variables having one as the dependent, the other independent, and the other being a confounding variable.
