I'm curious if I have coded my variables incorrectly for an analysis. Here's a brief explanation:

Independent variables:

X1: temperature (ordinal: 10 or 4 degrees C)

X2: treatment group (categorical: exposed to pathogen or not)

X3: sex (categorical...)

X4: index of body condition (scale: ranging from 0.15-0.24)

The Wald statistic was significant for all variables except X2 (P = 0.11), which confuses me, because looking at the results, the results (0 or 1, of course) are so different between the two categories of X2. Looking at the data, it seems 'wrong' that this variable is not significant. Could it be that there is an issue with my designation of body condition as a scale variable? While the distribution of these values are normal, the range is small, but the Exp(B) result is enormous 1.626e18, and the B = 48.8. I'm wondering if that could be falsely inflated somehow as a result of my variable coding.

Thoughts?

THANK YOU.
