Thanks Barbara,
Can you help me in Runs Test in minitab (Stat>Nonparametrics>Runs Test) and how much are the same?
Ehsan,
you made several postings in different threads with one and the same topic. Like Statistical Steven, Al Dyer and bobdoering stated in the thread
Run Chart in Minitab - Can I use Run Chart for Normality Test in Minitab that there seems to be a problem within your data, the same goes for the posting from Allattar in the thread
Minitab: Understanding Normality and What Chart To Use..
In this thread
P-value is 0.05 - Normal or non-normal data? bobdoering, Miner, Bev D, Statistical Steven and me tried to find sufficient answers to your questions, but it seems to me that we're running in circles.
Please re-read the answers already given in the threads posted above and if you still do not find what you're looking for, try to give us a better chance to understand by a more elaborate posting containing these steps:
- Describe the main goal of your analysis.
- Give a brief summary of the process examined.
- Attach your data in a format which provides the data itself in one labeled column, informations about subgroups in another column and additional informations (like materials used, operators, location, etc.) in further columns.
- List the steps and informations about the measurement system (was a Gage R&R study conducted, linearity tested, and so on).
- List the analysis steps you made so far and the conclusions you draw from them.
- Ask specific questions.
Even if this list doesn't answer your question, I hope it will help you anyway and surely it would help us to guide you to the analysis if we have these informations altogether.
Regards,
Barbara
