Summary: 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 \(K= [0, \infty)\times [0,\infty)\times[0,\infty)\) and \(\omega\) is non-negative increasing function on \(K\).
