[%]
Ratio of the standard deviation to the
mean value
s
:
Standard deviation
:
Mean value of the block
For sufficiently large samples it can
be said:
:
Standard deviation
:
Mean value
Range
R
Difference between the maximum
and the minimum values of the block
: Highest reading of the block
: Lowest reading of the block
Range
R
p
[%]
Range relating to the mean value
R
:
Range in percent
:
Mean value of the block
