Experimental design is an important statistical tool in process improvement. It studies the relationship between early variable (X) and variable-based variable (Y). By changing the levels of factors (x1,x2,...,xp), the results are applied to the problems to be solved. It is studied that this method can give the results of data analysis precision and accuracy than the general method, and it can be recognized as a statistical value showing the importance of variables that affect the process.
