The p-chart is a control chart used for monitoring the proportion of nonconforming items in a sample. The proportion is calculated by dividing the number of nonconforming items by the sample size. Since the proportion is a probability of success (nonconformance) in a single trial, the underlying distribution for a p-chart is binomial.
