Good afternoon, As indicated in the title, for a project I am interested in finding any (if at all) relation between the number of passengers in a car and the severity of an accident.
I am using JMP software and I am not great at the program by any means, but still I know a fair amount about certain analyses, but this one has me stumped.
As of yet, I have ran two different tests via JMP. The first was a simple Y by X distribution, which yielded me these results:
The second, which honestly was more of a guess, was using fit model Y by Construct, which yielded me this:
Now, when looking at the distributions, I can pretty much see that the overwhelming majority of all degrees of severity were with 0 passengers.
But for my second analysis, I don't quite understand the output, I don't know if it's the right test, and most importantly whether it is even necessary. It's for a project so I want to be thorough but I'm at wits end.
Any help would be appreciated! -Sam
