We report on study of transport properties of MgB2 single crystals. The normal state resistivity has been found to be anisotropic with resistivity ratio ρc/ρab = 3.5. In agreement with the results of band structure calculations the normal state Hall effect measurements with H//ab-planes and H//c-axis show two type carrier behavior. Below Tc, the in-plane as well as the out-of-plane Hall resistivity, ρxy and ρzx, display no sign change anomaly. Furthermore, both ρxy and ρzx have been found to scale with corresponding longitudinal resistivity with the same exponent β = 1.5.
