WebGenerate an Exponentially Weighted Moving Average (EWMA) chart based on the cycle time data, depicting the processing duration for customer orders in a car showroom over a specified period. The chart should have a target mean value of 30, a standard deviation of 2.13, and a smoothing factor ( λ ) set to 0.3.

WebJun 5, 2001 · Description: An EWMA control chart is a data analysis analysis technique for determining if a measurement process has gone out of statistical control. Similar to the cusum control chart, it is better than the standard xbar control chart for detecting small shifts in the process mean. For the EWMA control chart, we plot. yt = px¯t + (1 − p)yt−1.
