Control Limits for u-charts and c-charts
The lower and upper control limits, LCL, and UCL, are computed as:
u-chart LCL =
u-chart UCL =
c-chart LCL =
c-chart UCL =
The limits vary with
n
i
.
u
i
is the number of nonconformities per unit in the
i
th
subgroup. In general,
u
i
=
c
i
/
n
i
.
c
i
is the total number of nonconformities in the
i
th
subgroup
n
i
is the number of inspection units in the
i
th
subgroup
is the average number of nonconformities per unit taken across subgroups. The quantity
is computed as a weighted average
N
is the number of subgroups
