Since Scholes ended his retirement, United have racked up 34 points from a possible 36.
"A lot's been said about him coming back, whether it has been good or bad for us," Ferdinand told Sky Sports.
"But you can see in the results we've had since he's been back, the influence he's had. He's a fantastic player. Not only on the games you see out here but in training and around the training ground. He's an example for all the young players at the club."
