We obtain a Korovkin-type approximation theorem for Bernstein Stancu polynomials of rough statistical convergence of triple sequences of positive linear operators of three variables from H-omega (K) to C-B (K), where K = [0, infinity) x [0, infinity) x [0, infinity) and omega is non-negative increasing function on K.
