A Black Belt has run a full factorial experiment. The below image illustrates an interaction plot from the analysis. What level of interaction is there between these two factors?
A Black Belt runs an experiment on 2 different shifts comparing two different methods for data entry. The Black Belt wants to learn if there is a difference between methods. She suspects that shifts have impact on the response. However, she is not interested in optimizing the shift. What experimental design technique should the Black Belt use?
What is the AB interaction effect of:
Given the image below, what is the main effect of A?
A Black Belt is in the early stages of a problem solving effort. The Black Belt determines that the data gathered so far requires a DOE to gain additional insight and to understand which factors are important.There are 8 factors and budget is limited. What type of experiment is most appropriate?
You are about to run a t-test on shield thickness from 2 suppliers when you determine the data from one group is not normally distributed and cannot be transformed.Your next step would be to?
