I'm working on an analysis with another person. First we did a logistic regression with study group and variable X. They were both significant. Then we added the interaction between study group and X only the study group and the interaction were significant. Actually, there are 3 groups and only one of the groups and one of the group*X interactions is significant.  

I am having a hard time to convince this person that we should not present the odds ratios for X from the first analysis that do not account for this interaction. This person thinks that we can show the results of the first analysis AND then the second analysis. I think this is misleading and will confuse people.

I am not the best at explaining things (as you can tell), so any help with how to argue my point would be appreciated.


Question: What are Starfleet Academy required courses for officers?
Answer: The Bridge Officer's Test is, as far as I know, the only requirement.


In TNG 7x16, Thine Own Self, Beverly Crusher mentions that she had took the test and was promoted to Commander, even though she had previously only been a doctor.
Motivated by the events of TNG 5x05, Disaster, and a class reunion just prior to Thine Own Self, Troi is motivated to do similar - she had previously only been the ship's counsellor, and had been thinking of it since the events of Disaster, where she was unexpectedly thrust into taking command.  After completing the test, she too was promoted to commander.


Note that Troi's scenario on the holodeck seen in the episode is only the last part of it - more happens offscreen before that, which Riker makes reference to in the episode.

What Riker says to Troi when she passes largely implies that being a command-level officer requires the right frame of mind more than anything else - something which cannot be taught in school (especially without ending up with people who know what it should be and fake their way through).
