When measurements are taken using a reference scale, such as a pair of calipers, the resulting data are referred to as continuous data. Continuous data can take any value within a given range and are measured on a scale that can be subdivided. This type of data is crucial for precise quality control and statistical analysis in manufacturing and engineering.

The process performance index (Ppk) measures the performance of a process relative to the specification limits, accounting for the mean and variability of the process. It is an indicator of how well the process can produce output within the specification limits.
