This study focused on designing a training kit for learning design of experiment (DoE). A model has been established to provide a platform and facilities to conduct design of experiment. A system of ball rolling on a designated track has been made to fulfill this objective. Several factors could be set up to conduct real experiments repetitively. To verify the feasibility of this training kit, four different kind of experiments have been used to test the reliability of the factors levels and their response quality characteristics. Taguchi L8 and L9 matrices are used to find the optimum response time for a ball to complete the full travelling cycle, with quality objective of smaller the better, the conducted experiments achieved some results between Taguchi and Factorial designs that were used to confirm the experiments. The corresponded travelling time for Taguchi experiment and experimental solution of 24 factorial designs are 11.25 s and 11.43 s respectively, both falls within 90% confidence interval.
