a continuous, symmetric distribution:
P(r) is the probability of a value r, µ is the expectation value
(mean) and s is the
the values of m and s
to see the effect on distribution.
s corresponds to half the peak width at about 60% of full height.
Often, the full width at half maximum FWHM
peak value P(m) = .
Height of the curve at r =
m ± s: P(m ± s)
practice is an example of the Gaussian distribution in two
The significance of the
area under the Gaussian distribution should also be analysed.
