Dear All, I, yagneswar doing a project on quality improvement using six sigma. In the analysis part I preferred using minitab16. The case is that I have batch of components (6 objects/batch). And for each object six holes are there. Now I took the bore dia. of each hole (on both X, and Y-axis) on each object. Now I want to conclude my analysis as " is there any variation in hole-hole or in object-object". if the variation in hole-hole I need to change the tool, or if the variation in object-object then I need to change the fixture. So please help while selecting ANOVA I must use. Yours Yagneswar
