statistical tests

I require help in finding statistical tests to run for my survey research. My responses consist of nominal and ordinal variables but I only get mosaic plots and nothing concerning t-tests or Mann-Whitney U tests. I am not sure what I am doing wrong. "9" represents missing data. Any help would be appreciated

Change your Y Response column from Ordinal to Continuous. Then when you run Fit Y by X you will get the output where you will be able to perform your t-tests and your Mann Whitney (Wilcoxin in JMP)
Right click on the header for the column you want to set your number 9s to missing. Select Column Properties=>Missing Value Codes
