Create Control Chart
Explanation
Use this activity to create a control chart for a specific control plan line.
When creating Xbar and R chart, Xbar and S chart, np chart, and c chart,
the defined sample size and resulting sample size will be used.
- p chart- Gives information about the proportion of nonconforming units.
- np chart- Gives information about the number of nonconforming units
- c chart- Gives information about the number of nonconformities
- u chart- Gives information about the number of nonconformities per unit.
- Xbar and R chart - Gives information about the average and the range of
the result set of each analysis selected in the graph.
- Xbar and S chart - Gives information about the average and the standard
deviation of the result set of each analysis selected in the graph.
An analysis will not be included in creating a chart if any of the following
conditions exist.:
- The status of the data point is incomplete.
- The analysis header is canceled.
- The defined fixed sample size of the data point and the resulting sample
size of the analysis results do not match. (This does not apply for the p chart
and u chart.)
Prerequisites
- To create a control chart for a specific control plan line, the corresponding
control plan must exist, and at least two analyses must be complete for this
specific control plan line.
- The SPC check box for the control plan line must also be selected.
System Effects
As a result of this activity, a control chart for a specific control plan line
is created depending on the sample size.
