We performed an attribute study of our inspectors visual ability to detect a defect. I have attached a copy of our MiniTab chart in Word for those who may not have Minitab. I am trying to understand what this chart is telling me and should I consider doing anything. To me the results look positive but I wanted some feedback from others who may have more experience with these type of studies. We had 3 inspectors look at 50 samples in a random order and they each did it twice. Thanks.
