Companies that make analytical software are not in the business of teaching you how to make sense of data by understanding variation. They are in the business of selling you software. Have software build process behavior charts for you if you like, but only do so after verifying that the software-calculated process limits are correct using the instructions in this guide.
If you do not want to use the dataset provided here, a dataset with known process limits can be used. This alternate dataset should have at least one value that falls outside the process limits on the X chart and one value that is greater than the URL on the mR chart.
