5.2 Sigma Alarms
A Note regarding Sigma Alarms
Standard Deviation is a mathematical term that is, in essence, a band, equa-distant and on either
side of a line representing the average (mean) of a group of data points.
In a standard graph, there would be dashed lines on either side of a solid line representing the aver-
age.
These dashed lines are "scalable" in that the distance from that average (solid) line may be adjusted
closer to the mean (average), or farther away and are relative to the conditions that generate ever-
changing data plots.
