Because of possible effects from (110) twin planes and {ital a}-{ital b} anisotropy in YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}}, measurements on untwinned crystals are desirable. We have measured the Hall effect and resistivity simultaneously in untwinned single-crystal YBa{sub 2}Cu{sub 3}O{sub 7{minus}{delta}} with a superconducting transition temperature {ital T}{sub {ital c}}=93 K, with the magnetic field along the {ital c} axis. Below {ital T}{sub {ital c}}, the measured Hall resistivity reverses sign, becoming negative over a range of temperature and magnetic field, and the location and magnitude of the minimum is similar to that measured previously by others on twinned samples. These results show that the negative Hall resistivity is not caused by twin planes inducing guided vortex motion or vortex pinning. In addition, the exponent characterizing a scaling relation of the longitudinal to the Hall resistivity has a value consistent with that measured on thin films.
