A p chart can be used to plot what data on a control chart?
OPTIONS
- Any type of defects data
- Variable data on defects
- The number of defects in a sample
- Either the fraction or percent defective in order of time
ANSWER
Either the fraction or percent defective in order of time
EXPLANATION
The p chart does not plot the number of defects in a sample (a c or u chart is required). An p chart is an attribute chart and is not used for variables.
