Are all data in control? 3) Draw a pareto diagram by using data in Table 1. Please draw by monthly. 4) Draw a Control chart (X-bar Chart and R Chart) by using data in Table 1. To draw control chart, you need to find UCL (Upper Control Limit), LCL (Lower Control Limit), and CL (Control Limit) for both chart by using formula given below. Value for A2, D4 and D3 you can refer Figure 1 below. a. X-Bar Chart UCLI = X 4, R and LCLI = X - AR b. R Chart UCL = D. R and LCL DR
