Abstract
Statistical process control (SPC) is the process of analyzing a random sample of a process's output and determining if the process is generating products with characteristics that fall within a predetermined range. SPC provides a response to the issue of whether or not the process is working well. The suggested six sigma-based control chart for mean with Inter-quartile range (IQR) under moderate distribution outperforms the Shewhart (1931) [6] control chart for mean with moderate sample sizes.
