If you need to find a feature of JMP, you can also use Search JMP (JMP17 ->). Open your table, go to Help/Search JMP

Try to guess a search term (Normal is good starting point), pick something which could fit (Fit Normal)

and press Go.
It will open the correct platform for you to input in columns (and on the top guide where you can do the analysis)

By pressing OK you launch the analysis and the path is pre-configured for you, so in this case you will get normal distribution fitted to your data
