X charts operate effectively with smaller sample sizes than P- charts, but it is more involved to analyze the sample for an X chart since a measurement must be taken. A rule of thumb for the sample size of a P-chart is to have at least one defective in each sample. This can require a relatively large sample size in some cases. If the process is slow, an X chart will generally be a better choice since it functions with smaller sample sizes. An example of an X chart is average time to complete a mile run for one person. R charts are used to compute process ranges for variable data, and are generally used in concert with X charts....
