No. Number of the current block
n Number of measured readings
- Number of measured readings in the current/selected block
- Number of all measured readings in the current batch
Arithmetic mean of the current block with n measured readings
s Standard deviation for the arithmetic mean ; a measure for the variation
of individual measured readings (of a batch or block) around their common
mean value.
Min Lowest measured reading within a block
Max Highest measured reading within a block
R The range equals the difference between the highest and lowest measured
reading in a block or batch
V[%] Coefficient of variation, percentage variation of a series of measurements,
standard deviation in terms of the mean value , a sudden change in the
coefficient of variation indicates a change in process conditions
n<LSL Number of measured readings per block or batch below the lower specifi-
cation limit
n>USL Number of measured readings per block or batch above the upper specifi-
cation limit
Characteristic variables occurring during the control measurement for check-
ing a selected calibration: a description of the characteristic variables can be
found on page 66
