Quizplus · Accepted Answer

A scatter diagram is the best tool for analyzing the relationship between two variables, in this case, the number of process failures and the number of units produced. It can help determine if there is a correlation between the two variables and the strength of that correlation. This can then be used to make improvements and optimize the production process. A checklist, cause-and-effect diagram, and Pareto chart are helpful for other types of analysis and improvement projects.
