I am interested in the effect of the extend to which an occupation consists of routine codifiable tasks and individual job displacement. I have individual level survey data and use a logitlogistic model to account for the binary nature of the dependent variable. My inital results look like this, SEs are below the estimates (excerpt) enter image description here

Where column 1- 4 are different samples, with 1 being a pooled sample of all others.

Now it seems reasonable to control for each individuals education level which yields the following results: enter image description here

Where the education levels are dummy variables and high school is the comparison group.

Now my problem:

1.

It is reasonable to assume that the Routine Task Intensity of ones occupation correlates with the individuals education. I have though about doing an ANOVA but Routine Taks Intensity is not normaly distributed (though sample size is large ~21000). Is the any way to test correlation between education and Routine Taks Intensity? Maybe a non-parametric approach?

2.

How do I interpret the change in significance and effect size given that Routine Task Intensity still has roughly the same standard errors? My understanding of multicolinearity is that it inflates the variance. Can I say that education takes away from the explanatory power of Routine Taks Intensity? Since before Routine Task Intensity unjustly captured some of the effect that should actually be attributed to education?

Any help is greatly appreciated.

If any of my questions have already been covered I am grateful to anyone that can point me to the other posts. I have however spent several hours looking for similar questions and have not found one with a statisfactory answer with regards to my problem.

Changes in significance and effect size (though constant SEs) when controlling for a categorical variable. Correlation test & interpretation?
