What to do with questions related to statistical analysis of psychological variables?

Question

We previously had a question which was deleted which was as follows:

Classification of RT?

Hope this is the right place for this question: I have an experiment of two conditions & I have the reaction time (RT) for those two conditions (180 subjects and 500 RTs) the mean RT is significantly differ (t-test) between the two conditions. Now, I would like to construct a classifier which will learn the differences between those two conditions and will be able to classify new instances. I guess some dimension reduction is needed ? which classifier is recommended in such case ? Does anyone aware of such kind of work ? Any information on this would be appreciated.

The question has a psychological variable (i.e., reaction time) in the question, but the focus is on statistical analysis and machine learning.

Thus, in broad terms what should be done with questions that overlap psychology and statistics?

Answer 1

• If the psychology variable is secondary to the question, and it's really just a question about statistics then I'd migrate to http://stats.stackexchange.com/
• If the question relies heavily on content knowledge in psychology or cognitive science, even though it has a strong quantitative component (e.g., most psychometrics questions) then I'd let the question stay here; Stats.se might provide a good answer. However, there is general assumption that some questions fit on multiple sites and it's up to the person asking the question to decide in that case where they want to ask the question.

With regards to the question that motivated this meta post about RT classification, I think it's a borderline case. I think the question would get a better answer on stats.se and probably should have been migrated there.
