A newly obtained sample of inclusive electron-nucleon scattering data has been analyzed for precision tests of quark-hadron duality. The data are in the nucleon resonance region, and span the range 0.3<Q{sup 2}<5.0 (GeV /c){sup 2} . Duality is observed both in limited and extended regions around the prominent resonance enhancements. Higher twist contributions to the F{sub 2} structure function are found to be small on average, even in the low Q{sup 2} regime of {approx_equal}0.5 (GeV/c){sup 2} . Using duality, an average scaling curve is obtained. In all cases, duality appears to be a nontrivial property of the nucleon structure function. (c) 2000 The American Physical Society.
