I would like to compare sensors of a manufacturer A with those of a manufacturer B. As they provide different measurement magnitudes, I want to scale the variables such that it makes more sense to compare them:
But I'm not sure how exactly this should be done: Shall I scale the sensors
- among the manufacturers
- or across the population?
The latter probably makes no sense but the others? The upper four belong to manufacturer A and the lower four to manufacturer B.
This is how it looks when scaling per manufacturer:
