For an explanation of why the sample estimate is normally distributed, study the Central Limit Theorem. Variation of the Mean. The answer is that they use a different estimator. Note: Some people wonder why QI Macros results are a tiny bit different from some versions of other software. You should count the number of large squares (5 mm) between two QRS complexes (R-R interval), and afterwards you should count the number of remaining small squares (1 mm). In regular rhythm, we can calculate the heart rate counting the number of large and small squares between two QRS complexes. You can certainly have another chart for that, but the process monitoring chart’s limits are intended to monitor process stability, and these Shewhart stability limits are calculated differently. There are many different flavors of control charts, categorized depending upon whether you are tracking variables directly (e.g. Want to see us review a specific monitor? Deals.
