  A comparison study of world data for the structure function F2 for Iron, as
measured by both charged lepton and neutrino scattering experiments, is
presented. Consistency of results for both charged lepton and neutrino
scattering is observed for the full global data set in the valence regime.
Consistency is also observed at low x for the various neutrino data sets, as
well as for the charged lepton data sets, independently. However, data from the
two probes exhibit differences on the order of 15% in the
shadowing/anti-shadowing transition region where the Bjorken scaling variable x
is < 0.15. This observation is indicative that neutrino probes of nucleon
structure might be sensitive to different nuclear effects than charged lepton
probes. Details and results of the data comparison are here presented.
