Abstract
In the context of the averaging problem in relativistic cosmology, we provide a key to the interpretation of cosmological parameters by taking into account the actual inhomogeneous geometry of the Universe. We discuss the relation between “bare” cosmological parameters determining the cosmological model and the parameters interpreted by observers with a “Friedmannian bias,” which are “dressed” by the smoothed-out geometrical inhomogeneities of the surveyed spatial region.
