Using traditional methods, it takes 8.2 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 16 students and observed that they had a mean of 7.9 hours with a standard deviation of 1.5.
