Abstract
Pareto analysis, a notion that the vital few of 20% cause roughly 80% of outcomes, has been instrumental in quality improvement by signifying which systems account for a majority of errors. However, a Pareto chart must be made to test for statistical significance. Subjectivity of the data may lead analysts to determine an incorrect vital few. A graph of critical values and p-values aid analysts to show frequencies of occurrences of failure to remove that subjectivity.
