ASQ Six Sigma Green Belt Correlation Analysis Questions:

Question: A correlation analysis is used to provide a numeric value for which of the following types of relationships between two variables?

A) Random

B) Linear

C) Curvilinear

D) Causation

Answer: B – Linear.  This is a definition of correlation analysis. You could easily rule out random, though – there is no relationship between random events. It would also be helpful to see the articles on correlation coefficient and regression analysis to see this in action.
