Question 1 of 30

A Lean Six Sigma Green Belt is leading a project to enhance the efficiency of a chemical synthesis process. Preliminary observations suggest that the reaction time, a continuous variable, might significantly influence the purity of the synthesized compound, also a continuous variable. The Green Belt needs to visually assess the nature and strength of this potential relationship to guide further analysis and hypothesis testing. Which statistical tool, as per the principles outlined in ISO 18404:2015 for process improvement, would be the most appropriate initial graphical method to explore this relationship?
