The p chart is designed specifically to control the proportion of nonconforming units in a process. It is used when the data being collected is binary (i.e. a unit is either conforming or nonconforming). The $\overline { \mathcal { X } }$ chart is used to control the mean of a continuous variable, and the R chart is used to control the range of a continuous variable.
