For several measurements, the average
_
x indicates the average value, while
the standard deviation (Sdev) gauges the average deviation of the individual
measurements from this average value. More signicant standard deviations
indicate a more scattered series of measurements.
For normal measurement distributions,
68% of the measurements are within
_
x ± (1*Sdev),
95% of the measurements are within
_
x ± (2*Sdev),
99% of the measurements are within
_
x ± (3*Sdev)
