To do this in Excel, you need to calculate the weighted mean first. To calculate control limits for each SPC chart requires we estimate the standard deviation. A much more intuitive number is the standard deviation, which is simply the square root of the variance. Similarly, we build a series of values for a three-month moving average. Use Origin's built-in moving function or subrange notation to calculate statistics within a moving window. #4 Calculate SD . Next, we need to calculate the standard deviation of the closing price over the same number of periods. This page is a step-by-step guide to calculating variance and standard deviation. You just multiply the grade on each evaluation instrument (EI) by the fraction that EI represents of the final grade, then add them all together. Moving Standard Deviation is a statistical measurement of market volatility. In Six Sigma we want to describe processes quality in terms of sigma because this gives us an easy way to talk about how capable different processes are using a common mathematical framework.
