Thanks you very much.
Please help to clarify whether my analyse step is correct or not. I use one mean tutorial and Candy jmp file.
1. I plot distribution to find out whether it is normal distribution or not.
2. Select continuous fit ==> Normal
3. From fit normal red triangle ==> select goodness of fit
4. From note: Ho = The data is from normal distribution. Small p-value reject Ho. This mean data is not normal distribution.

From tutorial, they use test mean to verify. But this data is not normal distribution. We should use test median instead of test mean.
Question: Please confirm my understanding above correct or not. This is what I learnt many year ago.
If my understanding correct. Can I get test median from red triangle of histogram or not. If not, how can I get it.
